Although XScale isn't an architecture (it's simply an -implementation of ARMv5te), we do by tradition emit a specific -pre-define for it. We achieve this effect by adding an additional -feature bit to the xscale CPU definition that isn't part of the base -architecture. - -When I restructured the options last year I overlooked this oddity and -the result, of course, is that this configuration now fails to build -as intended. - -What happens is that the driver (correctly) constructs an architecture -for the xscale cpu name (as armv5te) and passes it in addition to the -CPU name. The backend code, on finding both a cpu and an architecture -specifies attempts to correlate the two and finds a difference due to -the additional feature bit and reports an inconsistency (fatally if --werror is specified). - -I think the best fix to this is to treat the xscale feature bit using -the same mechanism that we use for other 'quirks' in CPU -implementations and simply filter it out before comparing the -capabilities. It has the additional benefit that it's also the -simplest fix. - - PR target/86003 - * config/arm/arm-cpus.in (ALL_QUIRKS): Add xscale feature to the list - of bits to ignore when comparing architectures. - - -git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/branches/gcc-8-branch@261141 138bc75d-0d04-0410-961f-82ee72b054a4 ---- -Signed-off-by: Khem Raj <raj.khem@gmail.com> -Upstream-Status: Backport - - gcc/ChangeLog | 6 ++++++ - gcc/config/arm/arm-cpus.in | 4 +++- - 2 files changed, 9 insertions(+), 1 deletion(-) - -diff --git a/gcc/config/arm/arm-cpus.in b/gcc/config/arm/arm-cpus.in -index 96972a057e7..545321b0bbe 100644 ---- a/gcc/config/arm/arm-cpus.in -+++ b/gcc/config/arm/arm-cpus.in -@@ -268,7 +268,9 @@ define fgroup DOTPROD NEON dotprod - - # List of all quirk bits to strip out when comparing CPU features with - # architectures. --define fgroup ALL_QUIRKS quirk_no_volatile_ce quirk_armv6kz quirk_cm3_ldrd -+# xscale isn't really a 'quirk', but it isn't an architecture either and we -+# need to ignore it for matching purposes. -+define fgroup ALL_QUIRKS quirk_no_volatile_ce quirk_armv6kz quirk_cm3_ldrd xscale - - # Architecture entries - # format: --- -2.17.1 - |
