Bug ID: 123288
Summary: Many 32-bit libphobos tests FAIL on Linux/SPARC
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: d
Assignee: ibuclaw at gdcproject dot org
Reporter: ro at gcc dot gnu.org
Target Milestone: ---
Target: sparc64-unknown-linux-gnu
While testing a fix for PR d/123202 on Linux/sparc64, I found that many 32-bit
tests FAIL there. E.g. libphobos.phobos/std_math_hardware.d with the fix from
that PR applied:
$ ./std_math_hardware.exe
1 modules passed unittests
Illegal instruction ./std_math_hardware.exe
The stacktrace is like this:
Program received signal SIGILL, Illegal instruction.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
I have not investigated further since this issue is pre-existing.
