From 067fbc01b9e867b31c71091d62f0f9012dc9e41a Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Thu, 2 May 2024 08:18:19 -0400 Subject: Reduce optimization in hppa builds We're getting some odd errors in the lhash test on hppa. Analysis shows that the crash is happening randomly in various places, but always occurs during an indexed load of register r11 or r23. Root cause hasn't been completely determined, but given that: 1) hppa is an unadopted platform 2) asan/ubsan/threadsan shows no issues with the affected code elsewhere 3) The hppa build does not have threading enabled 4) reducing the optimization level to 01 quashes the problem The belief is that this is either a bug in gcc optimization, or an issue in the qemu emulator we use to test. Since this is causing CI failures, I'm proposing that we just lower the optimization level of the build to -01 to avoid the problem, and address it more throughly should an actual platform user encounter an error Fixes #24272 Reviewed-by: Matt Caswell Reviewed-by: Tomas Mraz (Merged from https://github.com/openssl/openssl/pull/24318) --- .github/workflows/cross-compiles.yml | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/.github/workflows/cross-compiles.yml b/.github/workflows/cross-compiles.yml index 5dc1b83f4e..0d0384c8e5 100644 --- a/.github/workflows/cross-compiles.yml +++ b/.github/workflows/cross-compiles.yml @@ -66,9 +66,11 @@ jobs: target: linux-armv4, tests: -test_includes -test_store -test_x509_store }, { + # gcc hppa seems to have some potential compiler issues + # with -O2 on this platform, reduce optimization to -01 arch: hppa-linux-gnu, libs: libc6-dev-hppa-cross, - target: -static linux-generic32, + target: -static -O1 linux-generic32, fips: no, tests: -test_includes -test_store -test_x509_store }, { -- cgit v1.2.3
