db's ARM/gcc-assembly doesn't work in Thumb mode, so the build fails when targeting ARM Thumb. Removing the --with-mutex=ARM/gcc-assembly configure option allows the build to complete successfully.
please provide emerge --info and build.log to allow to see the full error messages (that will also help in the future for finding possible duplicates of this bug for example) Thanks a lot

My CFLAGS="-O2 -mcpu=cortex-a53 -mfpu=neon-vfpv4 -mfloat-abi=hard" and the Cortex A53 is an ARMv8 processor. ARMv8 no longer supports the SWP instruction (see eg https://www.raspberrypi.org/forums/viewtopic.php?t=159827 ) which trips up GCC on ARM, with the error: libtool: compile: armv7a-unknown-linux-gnueabihf-gcc -c -I. -I/var/tmp/portage/sys-libs/db-6.0.35-r1/work/db-6.0.35/src -D_GNU_SOURCE -D_REENTRANT -O2 -mcpu=cortex-a53 -mfpu=neon-vfpv4 -mfloat-abi=hard /var/tmp/portage/sys-libs/db-6.0.35-r1/work/db-6.0.35/src/btree/bt_compare.c -o bt_compare.o >/dev/null 2>&1 /var/tmp/portage/sys-libs/db-6.0.35-r1/temp/ccGej9aa.s: Assembler messages: /var/tmp/portage/sys-libs/db-6.0.35-r1/temp/ccGej9aa.s:142: Error: swp{b} use is obsoleted for ARMv8 and later /var/tmp/portage/sys-libs/db-6.0.35-r1/temp/ccGej9aa.s:409: Error: swp{b} use is obsoleted for ARMv8 and later A modified ebuild dropping this line does not encounter this warning. Obviously removing this from every build may be detrimental to older ARM cores. Might make sense to make it a USE flag, and mask on armv8 profiles? I can provide a trivial ebuild patch for my modification if wanted.
Upstream's answer to this was just to rewrite the ASM code and entirely drop support for older ARM systems. I don't know if that's an acceptable compromise, esp. that we CANNOT backport the change due to the license switch. I'll detect >=arm7 and disable the flag there for now.
(In reply to Robin Johnson from comment #5) > I'll detect >=arm7 and disable the flag there for now. This issue was originally with <ARM7... Maybe just disable it always?
(In reply to Luke-Jr from comment #6) > (In reply to Robin Johnson from comment #5) > > I'll detect >=arm7 and disable the flag there for now. > > This issue was originally with <ARM7... Maybe just disable it always? Oh, you're right; the Cortex-A8 is ARMv7a. Possibly this assembly has just never worked in Thumb mode (OP has -mthumb in CFLAGS), and now also doesn't work in ARMv8 at all. This theory seems to agree with this ASM guide page on SWPB, which says it's been deprecated since ARMv6: http://www.keil.com/support/man/docs/armasm/armasm_dom1361289909499.htm In that case, with no better solutions, maybe let the compiler decide how best to optimize. I'm in favor of dropping it altogether.
Can either of you confirm that db-6.1, 6.2, 18.1 build fine with --with-mutex=ARM/gcc-assembly?

The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=c8762844e2a26ab7ed62a161195106652675828b commit c8762844e2a26ab7ed62a161195106652675828b Author: Robin H. Johnson <robbat2@gentoo.org> AuthorDate: 2019-05-08 21:19:50 +0000 Commit: Robin H. Johnson <robbat2@gentoo.org> CommitDate: 2019-05-08 21:24:42 +0000 sys-libs/db: compile-fix by dropping mutex=ARM/gcc-assembly This is a compile-fix so that old versions build on newer ARM hardware. The ARM assembly code does not work on newer hardware so you CANNOT use --with-mutex=ARM/gcc-assembly anymore. Specifically, it uses the SWPB op, which was deprecated [1] The SWPB op ALSO cannot be used in ARM-Thumb mode. >=sys-libs/db-6.1 uses LDREX instead, but that fix CANNOT be backported due differing licenses in the new versions (the new version is AGPL). Trust the compiler instead for older sys-libs/db versions, and just drop --with-mutex=ARM/gcc-assembly from the configure.
