From 76b414c3cdfd869ea051b0bb26d21a0b73a8b8da Mon Sep 17 00:00:00 2001 From: Andre McCurdy Date: Wed, 6 Jun 2018 21:34:38 -0700 Subject: gcc-target.inc: configure gcc for armv7ve targets to default to armv7ve Originally these ARM specific EXTRA_OECONF options were applied to both gcc for the target and gcc-cross. That lead to a compromise being made: gcc on the target was configured to default to an ARM architecture which was at least compatible with the target (but not necessarily an exact match) and gcc-cross was configured default to armv7a for both armv7a and armv7ve (to avoid gcc-cross rebuilds when switching between the two). However, when these ARM specific EXTRA_OECONF options were moved from gcc-configure-common.inc into gcc-target.inc (ie they were made to apply only to gcc on the target) the compromise no longer needed to be made. http://git.openembedded.org/openembedded-core/commit/?id=851937dde81de2a9ef54c5f19a78fb12fb82afd4 (From OE-Core rev: 3c368282741e9de1f96988e127b86a6a01b6a26f) Signed-off-by: Andre McCurdy Signed-off-by: Richard Purdie --- meta/recipes-devtools/gcc/gcc-target.inc | 11 ++++++----- 1 file changed, 6 insertions(+), 5 deletions(-) diff --git a/meta/recipes-devtools/gcc/gcc-target.inc b/meta/recipes-devtools/gcc/gcc-target.inc index b6e31f5d93..56e4b95af4 100644 --- a/meta/recipes-devtools/gcc/gcc-target.inc +++ b/meta/recipes-devtools/gcc/gcc-target.inc @@ -9,13 +9,14 @@ EXTRA_OECONF_PATHS = "\ EXTRA_OECONF_append_linuxstdbase = " --enable-clocale=gnu" -# ARMv6+ adds atomic instructions that affect the ABI in libraries built -# with TUNE_CCARGS in gcc-runtime.
