Description Rainer Orth 2024-02-05 14:07:13 UTC 
The gm2/extensions/run/pass/vararg2.mod test FAILs on Solaris/SPARC (32 and
64-bit) since its introduction:

FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O 
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O -g 
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O3 -fomit-frame-pointer 
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -O3 -fomit-frame-pointer -finline-functions 
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -Os 
FAIL: gm2/extensions/run/pass/vararg2.mod execution,  -g 

There are also gcc-testresults reports for Linus/s390x and Linux/m68k.

On Solaris, the test prints

parameter is hello world and length 0
executed /var/gcc/regression/master/11.4-gcc/build/gcc/testsuite/gm21/vararg2.x0 with result fail

All affected targets are big-endian, though I don't yet see how this affects
the test.

    [PR modula2/113768][PR modula2/114133] bugfix constants must be cast prior to vararg call
    
    This bug fix corrects the test codes below by converting the constant
    literals to the type required by C.  In the testcases below the values, 1
    etc were converted into the INTEGER type before being passed to a C
    vararg function.  By default in modula2 constant literal ordinals are
    represented as the ZTYPE (the largest GCC integer type node).
