Re: [Linaro-TCWG-CI] gcc-16-1550-g9244ea4bf556: Failure on aarch64

by Sam James

Could you file a glibc bug for this please? It needs some analysis to see if it's an FP or not. There's actually a suppression for -Os already there: if (elem < table_size) { /* Compare the byte sequence but only if this is not part of a range. */ /* The compiler might warn that idx may be used uninitialized, however it will be reached iff elem < table_size which means that it was properly set in the loop above. */ DIAG_PUSH_NEEDS_COMMENT; DIAG_IGNORE_Os_NEEDS_COMMENT (8, "-Wmaybe-uninitialized"); if (! is_range # if WIDE_CHAR_VERSION && __wmemcmp (n, &wextra[1], c1) == 0 # else && memcmp (n, &extra[idx + 1], c1) == 0 # endif ) { n += c1 - 1; goto matched; } DIAG_POP_NEEDS_COMMENT;

[PATCH] [arm] require armv7 support for [PR120424] (was: Re: [PATCH, FYI?] [arm] [vxworks] require thumb2 for pr120424.C)

It turned out that the regression report I got from linaro was related https://linaro.atlassian.net/browse/GNU-1599 While testing a configuration with -mfloat-abi=hard, -marmv7 is rejected because it doesn't have an FPU. Requiring thumb2 wouldn't have avoided this failure, but requiring armv7 is a proper fix for both problems. (sorry it me took so long; I'm still busy busy with other fp2sp-elimination-disabled-during-lra problems affecting arm) Without stating the architecture version required by the test, test runs with options that are incompatible with the required architecture version fail, e.g. -mfloat-abi=hard. armv7 was not covered by the long list of arm variants in target-supports.exp, so add it, and use it for the effective target requirement and for the option. Tested on arm-eabi, and also on arm-vx7r2 with gcc-14.

[automated CI mails] Need help with a regression Linaro CI notified me of

by Filip Kastl

Hi all. I got an automated mail about this GCC regression related to one of my commits. https://linaro.atlassian.net/browse/GNU-1578 The mail itself mentioned only a testsuite regression. I fixed that. However, this was also linked in the mail: https://ci.linaro.org/job/tcwg_bootstrap_build--master-arm-bootstrap_profil… That looks like a different regression. As far as I can tell, `make profiledbootstrap` is failing on arm. I have only very limited access to arm machines. I tried to reproduce this on an Aarch64 machine and didn't succeed. Could you check that this regression is still present on current trunk and/or help me reproduce it? Btw the "Instructions to reproduce the build" link doesn't work for me. I get "Request is not authorized". https://git-us.linaro.org/toolchain/ci/interesting-commits.git/plain/gcc/sh… Thanks, Filip Kastl
