fenv-*: Fix for FreeBSD/powerpc64 and NetBSD/powerpc

2024-01-19 Thread Bruno Haible 
On FreeBSD 14.0/powerpc64 and NetBSD 9.3/powerpc I'm seeing many test failures
of the fenv-* modules:

* FreeBSD 14.0/powerpc64 and FreeBSD 14.0/powerpc64le:

FAIL: test-fenv-env-2
FAIL: test-fenv-env-3
FAIL: test-fenv-env-4
FAIL: test-fenv-env-5
FAIL: test-fenv-except-state-2
FAIL: test-fenv-except-tracking-4
FAIL: test-fenv-except-tracking-1
FAIL: test-fenv-except-trapping-2.sh

* NetBSD 9.3/powerpc:

FAIL: test-fenv-env-2
FAIL: test-fenv-env-3
FAIL: test-fenv-env-4
FAIL: test-fenv-env-5

FAIL: test-fenv-except-state-2

This series of patches fixes them.


2024-01-19  Bruno Haible  

fenv-environment: Fix for NetBSD/powerpc.
* m4/fenv-environment.m4 (gl_FENV_ENVIRONMENT): For feupdateenv, use
the same configure test on NetBSD/powerpc as on glibc/hppa.
* doc/posix-functions/feupdateenv.texi: Mention the NetBSD/powerpc bug.

fenv-exceptions-trapping: Avoid a test failure on *BSD/powerpc*.
* tests/test-fenv-except-trapping-2.c (main): Skip the '4' tests also on
FreeBSD/powerpc* and NetBSD/powerpc*.

fenv-exceptions-state-c99: Fix for FreeBSD/powerpc64 and NetBSD/powerpc.
* m4/fenv-exceptions-state.m4 (gl_FENV_EXCEPTIONS_STATE): On
FreeBSD/powerpc64 and NetBSD/powerpc, set REPLACE_FESETEXCEPTFLAG.
* doc/posix-functions/fesetexceptflag.texi: Mention the FreeBSD and
NetBSD bug.

fenv-*: Avoid test failures on FreeBSD/powerpc64 and NetBSD/powerpc.
On these platforms, FE_ALL_EXCEPT contains additional bits.
* tests/test-fenv-except-tracking-1.c (FE_VXSOFT, FE_VXZDZ): Define
fallbacks.
(main): Allow fetestexcept(FE_ALL_EXCEPT) to contain FE_VXSOFT or
FE_VXZDZ in addition to FE_INVALID.
* tests/test-fenv-except-tracking-4.c (FE_VXSOFT): Define fallback.
