This test detects if the fallthrough in a switch statement falls to the
next case (good) or to the default case (bad).
* lib/tests/scaffold/44-switch-body-fallthrough-not-default.c: New file.
* build-aux/check-mescc.sh (mes_tests): Add it.
We detected the value in off64 in the test is not -1 as it should but 56
ones. This is because the rotation is applied as unsigned even with the
signed cast. This breaks many things in tcc.
* lib/tests/scaffold/50-compare-rotated-weird.c: New file.
* build-aux/check-mescc.sh (mes_tests): Add it.
This is a follow-up to commits
7a8a2fc517
mescc: x86_64 support: Refactor to abstracted assembly, add x86_64.
and
c9ba7a619b
mescc: Refactor variable declaration.
There was a debug "22" leaking in compile.scm. It should be a "0".
* module/mescc/compile.scm (init-local): Replace "22" with "0".
* lib/tests/scaffold/7v-struct-initialize-zeroes.c: New test.
* build-aux/check-mescc.sh (tcc_tests): Add it.
(xfail-tests): Remove lib/tests/scaffold/72-typedef-struct-def-local.c.
* lib/tests/scaffold/76-pointer-arithmetic.c (main): Use the right sizes
in the test for RISC-V architectures.
* lib/tests/scaffold/7k-for-each-elem.c (main): Same.
* lib/tests/scaffold/85-sizeof.c: Same.
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.
After a letter based digit, number based digits are off.
* lib/mes/abtol.c (abtol): Reset "m" for number based digit.
* lib/tests/stdlib/70-strtoull.c (main): Test it.
* lib/tests/stdlib/90-strtol.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

signed?.

value per failure.
