* gcc4.3.x: patch Makefile.in for cross compile badnessFrans Meulenbroeks2010-08-141-0/+29
| | | | | | | | | | | | | | When compiling gcc target code make passes -I(GMPINC) but this one points to the host dir (it is set to HOST_GMPINC which in oe points to tmp/sysroots/i686-linux/usr/include). This patch breaks the env var $(INCLUDES) in two and only uses the TARGET specific part for compiling libgcc and the crt stuff. The patch has been verified by baking all affected recipes with bitbake -c configure -b recipe Signed-off-by: Frans Meulenbroeks <fransmeulenbroeks@gmail.com>

| | | | | | | | | | * ldflags were being passed unnessarily so set LDFLAGS to nothing in Makefile.tpl and regenerate top level Makefile.in * Divide the patches individually earlier the patches were combined into one big patch * Shuffle the order of patches.

* gcc-4.3.3.inc : replace objc patch with undamaged one from gcc-patchesGraeme Gregory2009-11-271-27/+98
| | | | | | There is a one hunk peice of damage in the patch originally committed, as compared to the patch posted on gcc-patches. Replacing with the original patch enables platforms like arm oabi to compile again.

* gcc: update Maverick Crunch support to 20090908 versionMarcin Juszkiewicz2009-09-303-34/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Martin W. Guy page http://martinwguy.co.uk/martin/crunch/ The 20090908 version * performs single and double precision floating point in the FPU (add, sub, mul, neg, abs, cmp and conversions from single and double precision floats to integral types). * by default, disables the floating point cfnegs and cfnegd instructions, which fail to convert 0 to -0 as they should. You can re-enable them with the -funsafe-math-optimizations flag, which is one of those enabled by -ffast-math (gcc-4.3 has an even more specific -fno-signed-zeros flag, which is one of those enabled by -funsafe-math-optimizations). * by default, does not respect denormalised values, so the smallest representable values are ±2-126 for floats and ±2-1022 for doubles instead of the usual ±2-149 and ±2-1074. * has a -mieee flag, which enables handling of denormalized values by disabling all the buggy instructions. With this, floating point addition, subtraction, negation, absolute value and conversion between floats and integer types are performed in software, leaving only floating point multiplication and comparison performed in hardware. * has no negative impact on regular ARM code generation. * always works round the hardware bugs in the FPU and no longer has the -mcirrus-fix-invalid-insns flag since chip development has stopped and all existing silicon has the same bugs except for the original revision D0 which is not supported. * passes GCC's IEEE testsuite except for the one specific test that checks for correct handling of denormalized values. With -mieee it passes all the math tests. * passes all other testsuites that I've tried (see below) including the stringent "paranoia" floating point IEEE conformance test. * produces the fastest Maverick code yet: 5.94 MFLOPS according to FFTW's tests/bench -opatient cf1024 benchmark and LAME takes 2m25 to encode that 30-second WAV file on a 200MHz EP9307 (compared to 5.4 and 2m30 for the futaris patches for 4.1.2 and 4.2.0). * does not use the FPU's buggy 64-bit integer instructions unless the new -mcirrus-di flag is given. Programs that do a lot of 64-bit integer operations (add, sub, mul, neg, abs, shifts) may be faster using this, but rigorous testing will be necessary to ensure that bad code is not being produced. OpenSSL's testsuite fails if this is enabled. There is more detail at the head of the arm-crunch-cirrus-di-flag.patch file. Known bugs * C: Values held in Maverick registers are not restored when performing a setjmp/longjmp pair. There is a fix to glibc for this in a message to the linux-cirrus mailing list. * C++: Similarly, exception unwinding (performing a throw back to a catch block in a different function) does not restore floating point and 64-bit values held in Maverick registers. * C++: Some C++ files will not compile, saying ".save {mv8}" Error: register expected although the same files will compile with optimization disabled. There is a patch to make binutils recognize these registers in the .save macro in a message to the linux-cirrus mailing list.
* gcc: get rid of fix-ICE-in-arm_unwind_emit_set.diffDirk Opfer2009-06-251-28/+0
| | | | | | | | | Remove fix-ICE-in-arm_unwind_emit_set.diff from gcc versions >= 4.2.1 upstream gcc already includes this fix. Instead of patching arm_unwind_emit_set the patch was modified and slipped into thumb_pushpop and can cause a gcc segfault. Signed-off-by: Dirk Opfer <dirk@do13.de>
* gcc 4.3.3: add ep93xx patches from Martin W. GuyMarcin Juszkiewicz2009-06-0228-0/+2856
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Patchset taken from http://martinwguy.co.uk/martin/crunch/ Text from page: On 10 March there were no known bugs in this stuff (again). On 19 March libvorbisenc managed to find a bug in GCC whereby it incorrectly optimizes certain code sequences that use single-precision floats. The Maverick code generator exhibits similar symptoms for the same code, but only at optimization levels -O2 and above, so the fastest reliable optimization options for Maverick at present are -O -ffast-math. I've been working on GCC-4.3.3 to make it generate working code for the Cirrus Logic MaverickCrunch FPU, as found in their ARM-based EP9302, EP9307, EP9312 and EP9315 chips, making floating point-intensive code about 2.5 times faster. This follows on from Hasjim Williams' earlier work with gcc-4.1.2 and 4.2.0, a bundle of his more recent ideas and more hacks from me. If you want to understand the patches themselves, there is an article about the MaverickCrunch FPU and GCC's problems with it on the Debian wiki [1] and I have added commentary at the top of the individual patch files. 1. http://wiki.debian.org/ArmEabiMaverickCrunch Signed-off-by: Marcin Juszkiewicz <marcin@juszkiewicz.com.pl> Acked-by: Koen Kooi <koen@openembedded.org> Acked-by: Tom Rini <trini@embeddedalley.com>
