M1 immediates are limited to 31-bit before they become negative.
* module/mescc/x86_64/as.scm (x86_64:value->r, x86_64:r-cmp-value,
x86_64:r-long-mem-add, x86_64:r-and): Limit M1 immediate to #x80000000.
* lib/tests/scaffold/67-m1-overflow-check.c: New test.
* build-aux/check-mescc.sh (mes_tests): Add it.
Reuported by Andrius Štikonas <andrius@stikonas.eu> via IRC.
* lib/tests/assert/50-assert.c (main): Initialize local f.
* lib/tests/scaffold/21-char-array.c (main): Likewise.
These inexplicably avoid segfaults with gcc-12.2.0.
* lib/tests/posix/50-open-read.c (main)[__GNUC__ > 11]: Use malloc
instead of local allocated string.
* lib/tests/scaffold/7i-struct-struct.c (main)[__GNUC__ > 11]:
Initialize all fields of struct.
* lib/tests/scaffold/t.c (main): Likewise.
* lib/tests/scaffold/70-stdarg.c (stdarg1, stdarg2, stdarg3): Pass int
to va_arg instead of char to avoid gcc trap "warning: 'char’ is promoted
to ‘int’ when passed through ‘...’ [enabled by default] (so you should
pass ‘int’ not ‘char’ to ‘va_arg’) if this code is reached, the program
will abort".
This fixes running as lib/tests/scaffold/54-argv-i686-unknown-linux-gnu-tcc.
* lib/tests/scaffold/54-argv.c (main): Compare only first 26 characters
of argv[0].
This fixes 36-compare-arithmetic.c
* module/mescc/i386/as.scm (i386:r0/r1, i386:r0%r1): Do not reset
signed?.
* module/mescc/x86_64/as.scm (x86_64:r0/r1, x86_64:r0%r1): Likewise.
* lib/tests/scaffold/36-compare-arithmetic.c (main): Use unique exit
value per failure.
This adds minimal Hurd support by implementing the _exit function.
