If desired I can run tests on the native arm device, but need a few directions on how to run them.
(In reply to tt_1 from comment #1) > If desired I can run tests on the native arm device, but need a few > directions on how to run them. Does the test suite pass? Do: 1. emerge -v1 --with-test-deps compiler-rt-sanitizers 2. FEATURES=test emerge -v1 compiler-rt-sanitizers
interesting, thank you for showing me how to test this package. it doesn't look good though, the build never made it to the test-phase but breaks when compiling a sort of bootstrap code for the tests: [57/61] cd /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt_build/lib/scudo/standalone/tests && /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt_build/lib/llvm/16/bin/clang -O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard -fomit-frame-pointer -Wall -Wno-unused-parameter -Wno-unknown-warning-option -Wthread-safety -Wthread-safety-reference -Wthread-safety-beta -g -Wno-covered-switch-default -Wno-suggest-override -DGTEST_NO_LLVM_SUPPORT=1 -DGTEST_HAS_RTTI=0 -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/../third-party/unittest/googletest/include -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/../third-party/unittest/googletest -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/include -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone/include -DGTEST_HAS_RTTI=0 -g -Wno-mismatched-new-delete -march=armv7-a -mfloat-abi=hard -c -o ScudoUnitTestsObjects.wrappers_c_test.cpp.armhf.o /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone/tests/wrappers_c_test.cpp FAILED: lib/scudo/standalone/tests/ScudoUnitTestsObjects.wrappers_c_test.cpp.armhf.o /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt_build/lib/scudo/standalone/tests/ScudoUnitTestsObjects.wrappers_c_test.cpp.armhf.o cd /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt_build/lib/scudo/standalone/tests && /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt_build/lib/llvm/16/bin/clang -O2 -pipe -march=armv7-a -mfpu=vfpv3-d16 -mfloat-abi=hard -fomit-frame-pointer -Wall -Wno-unused-parameter -Wno-unknown-warning-option -Wthread-safety -Wthread-safety-reference -Wthread-safety-beta -g -Wno-covered-switch-default -Wno-suggest-override -DGTEST_NO_LLVM_SUPPORT=1 -DGTEST_HAS_RTTI=0 -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/../third-party/unittest/googletest/include -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/../third-party/unittest/googletest -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/include -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone -I/var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone/include -DGTEST_HAS_RTTI=0 -g -Wno-mismatched-new-delete -march=armv7-a -mfloat-abi=hard -c -o ScudoUnitTestsObjects.wrappers_c_test.cpp.armhf.o /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone/tests/wrappers_c_test.cpp /var/tmp/portage/sys-libs/compiler-rt-sanitizers-16.0.0_rc2/work/compiler-rt/lib/scudo/standalone/tests/wrappers_c_test.cpp:223:13: error: use of undeclared identifier 'mallopt' EXPECT_EQ(mallopt(-1000, 1), 0);

The masks are based on compiler-rt/cmake/Modules/AllSupportedArchDefs.cmake [1]. Admittedly, I haven't updated them in a while but FWICS ARM32 still isn't listed for most of the targets you've listed. I'll update the others.

Thanks for fixing up the mask, I guess this can be closed and I'll open a new bug report for the failure in bootstrapping the tests.
