* gcc-configure: Enable initfini-arraySaul Wold2016-09-201-0/+4
| | | | | | | | | | | | | This adds the correct support for initfini-array which replaces .init and .fini with .init-array and .fini-array. There is no appreciable size difference with this change. The change is needed since configure will not correctly detect support when building cross-compilers.

* gcc-configure-common.inc: drop --enable-target-optspace from configureAndre McCurdy2016-02-021-8/+0
| | | | | | | | | | | | | | | | | | | | | | Configuring gcc with --enable-target-optspace (which causes gcc to append "-g -Os" to the default CFLAGS_FOR_TARGET and so force libgcc etc target libraries to always be optimised for size) dates back to the very first commit in oe-core git in 2005 (for gcc 3.4.3). Configuring gcc with --enable-target-optspace is not done widely elsewhere (it's not used for Ubuntu or Fedora host gcc, the Linaro binary toolchain or in Buildroot since early 2015). Sometime around gcc 4.5.x it caused problems for powerpc and so was disabled for that architecture: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810 This patch removes --enable-target-optspace completely (ie powerpc is no longer a special case) and allows optimisation of libgcc etc to be controlled directly by the flags present in TARGET_CFLAGS.

* machine/include: drop tune-cortexm*.inc and tune-cortexr4.incAndre McCurdy2016-02-021-2/+0
| | | | | | | | | | | | The Cortex M1, M3 and R4 CPU tuning files are poorly tested (if at all). They have no obvious users either inside or outside oe-core. Until OE officially gains support for CPUs without an MMU, these tuning files are probably better maintained outside of oe-core (e.g. in a separate meta-nommu layer).

* gcc: Update default Power GCC settings to use secure-pltMark Hatle2015-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | The gcc default, bss-plt, will cause errors when using the prelinker. All other distributions that I am aware of are using the the secure-plt. For an explanation of the differences, the gcc docs: Current PowerPC GCC accepts a `-msecure-plt' option that generates code capable of using a newer PLT and GOT layout that has the security advantage of no executable section ever needing to be writable and no writable section ever being executable. PowerPC ld will generate this layout, including stubs to access the PLT, if all input files (including startup and static libraries) were compiled with `-msecure-plt'. `--bss-plt' forces the old BSS PLT (and GOT layout) which can give slightly better performance. The security of the new PLT and ability to run the prelinker outweigh any performance penalty. The secure-plt is enabled by default. The old bss-plt can be enabled by selecting 'bssplt' in the DISTRO_FEATURES. Signed-off-by: Mark Hatle <mark.hatle@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com>

* arch-mips.inc: Change definition of TRANSLATED_TARGET_ARCHMark Hatle2015-01-291-0/+2
| | | | | | | | | | | | | | | | | | | | [YOCTO #7230] In certain system configurations TRANSLATED_TARGET_ARCH will not expand in the right order for gcc-cross-candian-mips64n32 to be generated properly. This will cause SDKs to fail to generate properly. Changing the global definition of TRANSLATED_TARGET_ARCH always expands the ABIEXTENSION, which causes the OVERRIDES to pick it up as well. This effectively defines a new class of overrides for the 'n32'. The side effect is that we need to duplicate some mips64 overrides, and redefine others that were previously 'n32' or 'mips64' exclusive to have the correct semantics.

* gcc: Rework shared workRichard Purdie2014-12-031-0/+1
| | | | | | | | | | | | | | | | | | | The current implementation of shared work for gcc is at best confusing. It relies on the fetch/unpack/patch tasks having exactly the same stamps and if this gets broken for some reason, its hard to figure out what the problem is. It also leads to complex code in bitbake. The benefits of shared work for gcc are clear but a better approach is needed. This patch adjusts things so that a single new recipe (gcc-source) provides the fetch/unpack/patch/preconfigure tasks, the rest of gcc simply depends on these tasks and have no fetch/unpack/patch tasks of their own. This means we should get the significant benefits (disk usage/performance) of the single source tree but in a way which has less potential for problems and is easier for people to understand. The cost is an extra recipe/some inc files which is probably a good tradeoff. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

* gcc: update compiler architecture to match gcc-runtime (armv6, armv7a)Peter A. Bigot2014-08-151-0/+7
| | | | | | | | | | | | | | | | | | | | The gcc-runtime recipe builds the gcc libraries including libstdc++ with $TARGET_CC_ARCH flags, which include -march=FOO flags that affect whether atomic instructions are available. This causes an ABI incompatibility when the compiler by default generates code for less capable architectures. For example, gcc-runtime libraries on a Cortex-A8 are built with a different C++11/C++14 mutex implementation than is used code compiled outside OE and without architecture-specific flags. This commit fixes the problem specifically for ABI issues related to atomic instructions available in ARMV6 and subsequent architectures. Other ABI incompatibilities may remain in other architectures. See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=62100 Signed-off-by: Peter A.

* gcc-configure-common: Address problems with gengtypeRichard Purdie2014-06-171-0/+2
| | | | | | | | | | | | | | | | The gengtype patch we apply to gcc aims to ensure that the build and host config headers don't get confused. We're seeing build failures where both headers have been included, likely due to a race over the configuration files. It seems the gengtype-lex.c file isn't being regenerated when it should and the unconditional inclusion of bconfig.h is resulting in these issues. The fix is therefore to remove the file, forcing its regeneration. [YOCTO #6393] Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* gcc: Clean up configure_prepend and fix for mingwRichard Purdie2014-06-011-7/+1
| | | | | | | | | | | | | | | | | | | The do_configure_prepend was duplicated in gcc-4.X.inc and gcc-configure-common.inc leading to confusion when reading the resulting do_configure task where the file was processed twice. The only difference was the removal of the include line for gcc 4.8/4.9. On mingw were were seeing two issues, firstly that the if statements meant the values we wanted weren't being set, the second that the include paths were still wrong as there was no header path set. To fix the first issue, the #ifdef conditionals were removed, we want to set these things unconditionally. The second issue is addressed by setting the NATIVE_SYSTEM_HEADER_DIR variable here (it was already set in t-oe). Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* gcc-common: Only apply fpu settings to target gccRichard Purdie2014-05-011-1/+1
| | | | | | | | | | | Within the OE build environment, we supply the correct fpu settings. These only need to be spelt out for the on-target gcc.

* gcc: Drop ARCH_FLAGS_FOR_TARGET usageRichard Purdie2014-04-301-6/+0
| | | | | | | | | | | | | | | As far as I can tell this variable is now completely unneeded. It would only ever get used in target builds and these are now correctly done in the target environment namespace, not any of our cross environments. As such, CC and other variables contain the correct compilers and other tune options and these are correctly picked up when building libgcc, libstdc++ and others. I tried to figure out where else these would make any sense and couldn't find anything. Builds appear fine without them so lets drop the complexity including the patch adding in this flag to gcc.

* gcc/libtool/perl: Fix various path to sed-native problemsRichard Purdie2013-09-261-0/+1
| | | | | | | | | | | | | | | | | | If sed-native is built before these programs, hardcoded paths to sed-native can end up in scripts and other parts of the system which may cause issues if they are later used from sstate and sed-native is not installed. To avoid this, this patch changes the global site configuration to specify that plain "sed" is fine to be used. We need to spell this out for gcc since it doesn't see the site files since we don't autoreconf it. We can remove the values from libtool. We tell perl to use "/bin/sed" since it requires a path and the system sed should be just fine for it.

* gcc-configure-common.inc: Stop gcc looking at build system pathsRichard Purdie2012-04-151-0/+4
| | | | | | | | | | | | | | | | | There were puzzling failures when you make a force recompile of any gcc component. The error was in do_configure with cross-compilation badness being detected in config.log files. gcc is different in that many of the config.log files are generated during the do_compile phase. This means this host contamination issue has always been present but only shows up on a rebuild. The fix is to force the appropriate configuration variable to "none required" then gcc won't look in the bad locations.

* gcc: Ensure that the shared source directory shared the same sstate hashesRichard Purdie2012-01-231-15/+0
| | | | | | | | | | | | | | | | | | | | The fetch/unpack/patch/headerfix tasks are shared and hence their sstate hashes should also match. Sadly this is not the case since: a) gcc-runtime applies an additional patch b) The do_headerfix task was missing from libgcc c) The do_headerfix task is a shell task and hence depends on all exported variables which can vary between cross and target recipes. To fix this, the patch moves the patch to the common code, adds the headerfix task to a common include file and disabled shell dependencies on the do_headerfix task since its clear in this case we don't need thsoe dependencies since we just call sed. With this patch applied, all these recipes now share common sstate checksums. Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
* Introduce multiarch DISTRO_FEATUREJulian Pidancet2011-11-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a distro feature which enables gcc to produce both 32bit and 64bit code, and enables binutils to operate on both 32bit and 64bit binaries. It differs from multilib toolchains in that it does not require to compile a version of the libc for each architecture variant. However, the code produced for the secondary architecture will not be linkable against the libc. v2: - Renamed the feature name from "biarch" to "multiarch". The GCC installation manual claims that the mips-linux can be made a tri-arch compiler (http://gcc.gnu.org/install/configure.html) - For x86_64, the compiler is made bi-arch by default, so nothing has to be done in particular. - I analyzed the gcc/config.gcc from GCC sources and added in this patch all the architectures that could be made biarch with the version of gcc currently used in OE, which are powerpc, and sparc, in addition to x86. mips and s390 will probably be supported in future versions of gcc. For x86 and sparc, only the --enable-targets=all option is valid to make this work (this option doesn't have any other side effects than making the compiler bi-arch). For powerpc, I used the --enable-targets=powerpc64 option (although 'all' also works). Note: - Untested on powerpc and sparc. But I believe it works the same as with x86. - gcc in meta-toolchain is also made multiarch. Signed-off-by: Julian Pidancet <julian.pidancet@gmail.com>

Change the way to make it work: * The configure option --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} can replace the sed command, see the code in configure: if test "x$with_headers" != x; then glibc_header_dir=$with_headers This has the same effect as the sed command: sed -i 's:^\([ ]*\)glibc_header_dir=\"${with_build_sysroot}/usr/include\": ... so add the --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} to gcc-configure-cross.inc( not add to gcc-configure-common.inc, since not all the gcc building need this, the one which has its own do_configure doesn't need it). * Move t-oe from ${T} to ${B}/gcc, so that the patched Makefile.in can read it easily, please see the commit for gcc-4.5.1 and gcc-4.6.0. * Use the defaults.h in ${B}/gcc instead of ${S}/gcc, and the patched configure.ac(configure) can read it correctly, please see the commit for gcc-4.5.1 and gcc-4.6.0. * The gcc-crosssdk.inc used sed to edit ${S}/config/*/linux*.h to change the GLIBC_DYNAMIC_LINKER, which made the source incompatible. To make the source compatible: - Use: sed -i ${S}/gcc/config/*/linux*.h -e \ 's#\(GLIBC_DYNAMIC_LINKER[^ ]*\)\( *"/lib.*\)#\1 SYSTEMLIBS_DIR\2#' so entries in the files that look like: #define GLIBC_DYNAMIC_LINKER64 "/lib64/ld-linux-x86-64.so.2" would become #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2" and we define SYSTEMLIBS_DIR in defaults.h. NOTE: #define GLIBC_DYNAMIC_LINKER64 (SYSTEMLIBS_DIR "/ld-linux-x86-64.so.2") doesn't work in in the following define: #define LINUX_DYNAMIC_LINKER \ CHOOSE_DYNAMIC_LINKER (GLIBC_DYNAMIC_LINKER, UCLIBC_DYNAMIC_LINKER) so use #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2" 5) Add do_configure_prepend to gcc-configure-common.inc and remove the one in gcc-crosssdk.inc, this makes it easy to share the source, otherwise we need do extra changes in gcc-configure-sdk.inc. 6) Use "cat > file <_EOF" to replace the "echo > file" Signed-off-by: Robert Yang <liezhi.yang@windriver.com>

* gcc: fix check for target libc ssp supportKevin Tian2010-09-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | gcc uses hardcoded path "${with-build-sysroot}/usr/include" to check target libc ssp support. Based on GLIBC version strings in features.h in that search path, gcc knows whether target (e)glibc implements stack protector itself. However this breaks meta-toolchain, which actually has target libc headers installed under {with-build-sysroot}/opt/... This way features.h is not found and thus gcc-crosssdk-intermediate thinks that target (e)glibc doesn't support ssp. Later when building eglibc-nativesdk, undefined reference to "__stack_chk_guard" occurs which was caused by: o eglibc do_configure found that gcc-crosssdk-intermediate supports ssp, and thus enable -fstack-protector for nscd o eglibc itself supports stack smash proctection for some architectures such as i386, x86-64, etc. It's expected to use its own method to provide stack protection, instead of relying on gcc. So eglibc rtld.os doesn't export __stack_chk_guard to other modules o then when installing nscd objects, gcc-crosssdk-intermediate sees the flag "-fstack-protector", while it thought this eglibc doesn't implement ssp itself, so gcc turns to the alternative to find a valid __stack_chk_guard exported. eglibc doesn'g export it, while gcc-crosssdk-intermediate itself disables libssp. Then the undefined reference happens. If enabling libssp for gcc-crosssdk- intermediate, it may also work-around this issue. But the ideal fix is still to replace hard coded path with the actual one where target libc gets installed. glibc-nativesdk doesn't encounter this issue because it thinks gcc doesn't support ssp, and thus doesn't enable "-fstack-protector" for nscd.

* gcc: upgrade gcc for powerpc to version 4.5.0Dongxiao Xu2010-09-171-1/+2
| | | | | | | | | | | | | | Fix one parameter order issue for base_contains function, which impacts glibc build under new gcc. Add new judge code to determine whether <altivec.h> is needed. This fixes the mpeg2dec build failure under new gcc. Use O2 as the optimization flag to tinylogin as it will meet segfault if compiled by gcc-4.5.0 when enable both frename-registers and Os options. Use O2 instead. Signed-off-by: Dongxiao Xu <dongxiao.xu@intel.com>
* Major layout change to the packages directoryRichard Purdie2010-08-271-0/+107
Having one monolithic packages directory makes it hard to find things and is generally overwhelming. This commit splits it into several logical sections roughly based on function, recipes.txt gives more information about the classifications used. The opportunity is also used to switch from "packages" to "recipes" as used in OpenEmbedded as the term "packages" can be confusing to people and has many different meanings. Not all recipes have been classified yet, this is just a first pass at separating things out. Some packages are moved to meta-extras as they're no longer actively used or maintained.
