Re: [Linaro-TCWG-CI] gcc patch #142457: 2 regressions on aarch64

by Dora, Sunil Kumar

Hello Linaro CI Team, This looks unrelated to the patch. It only defines LINK_SSP_SPEC inside the DEFAULT_LIBC == LIBC_MUSL block of gcc/config/linux.h plus two rs6000 headers, so nothing from it is compiled into an aarch64-linux-gnu build. To be sure I built aarch64-linux-gnu cross compilers from master with and without the patch using the same configure flags as this CI, and xgcc -dumpspecs output is byte-identical, while the same tree targeted at aarch64-linux-musl does show the new -lssp_nonshared spec. The failing test is a gcov prime-paths count, and the build's own results.compare.txt says "No regression found in 3 common sum files". Happy to dig further if anyone sees a connection I am missing. Thanks, Sunil Dora ________________________________ From: ci_notify(a)linaro.org <ci_notify(a)linaro.org> Sent: Tuesday, September 1, 2026 10:48 AM To: Dora, Sunil Kumar <SunilKumar.Dora(a)windriver.com> Cc: raj.khem(a)gmail.com <raj.khem(a)gmail.com> Subject: [Linaro-TCWG-CI] gcc patch #142457: 2 regressions on aarch64 CAUTION: This email comes from a non Wind River email account!
