From a22b97aff811566399765d755daffddb28f82857 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Sat, 3 Mar 2018 12:24:39 -0800 Subject: glibc: Compile using thumb2 for arch > armv5 if user chooses For arm we enforce ARM mode regardless of ARM_INSTRUCTION_SET choice from config metadata, glibc works fine with thumb2 for armv7+ so limit the restriction to armv5 and lower, tested on rpi3 works equally well as arm mode glibc and sheds about 0.5MB in size for main package alone. Other glibc build packages also gets smaller ARM: 2696 KiB libc6 Thumb2: 2132 KiB libc6 Signed-off-by: Khem Raj Signed-off-by: Richard Purdie --- meta/recipes-core/glibc/glibc-collateral.inc | 3 ++- meta/recipes-core/glibc/glibc.inc | 3 ++- 2 files changed, 4 insertions(+), 2 deletions(-) (limited to 'meta/recipes-core/glibc') diff --git a/meta/recipes-core/glibc/glibc-collateral.inc b/meta/recipes-core/glibc/glibc-collateral.inc index de859d5ce9..aa871ac83d 100644 --- a/meta/recipes-core/glibc/glibc-collateral.inc +++ b/meta/recipes-core/glibc/glibc-collateral.inc @@ -7,7 +7,8 @@ HOMEPAGE = "http://www.gnu.org/software/libc/index.html" # This needs to match with glibc.inc, otherwise glibc-scripts and glibc-locale # will fail to find main glibc, for details see # http://lists.openembedded.org/pipermail/openembedded-core/2015-January/100679.html -ARM_INSTRUCTION_SET = "arm" +ARM_INSTRUCTION_SET_armv4 = "arm" +ARM_INSTRUCTION_SET_armv5 = "arm" deltask do_fetch deltask do_unpack diff --git a/meta/recipes-core/glibc/glibc.inc b/meta/recipes-core/glibc/glibc.inc index 21bbdc2ad0..361a6fde10 100644 --- a/meta/recipes-core/glibc/glibc.inc +++ b/meta/recipes-core/glibc/glibc.inc @@ -57,7 +57,8 @@ INHIBIT_DEFAULT_DEPS = "1" # This needs to match with glibc-collateral.inc, otherwise glibc-scripts and glibc-locale # will fail to find main glibc, for details see # http://lists.openembedded.org/pipermail/openembedded-core/2015-January/100679.html -ARM_INSTRUCTION_SET = "arm" +ARM_INSTRUCTION_SET_armv4 = "arm" +ARM_INSTRUCTION_SET_armv5 = "arm" # glibc uses PARALLELMFLAGS variable to pass parallel build info so transfer # PARALLEL_MAKE into PARALLELMFLAGS and empty out PARALLEL_MAKE -- cgit 1.2.3-korg
