> Reduce false positives for -Wnonnull for VLA parameters [PR98541] > > This patch limits the warning about NULL arguments to VLA > parameters declared [static n]. > > PR c/98541 > > gcc/ > * gimple-ssa-warn-access.cc > (pass_waccess::maybe_check_access_sizes): For VLA bounds > in parameters, only warn about null pointers with 'static'. > > gcc/testsuite: > * gcc.dg/Wnonnull-4: Adapt test. > * gcc.dg/Wstringop-overflow-40.c: Adapt test. This patch caused a testsuite regression: there's now an "excess error" failure for gcc.dg/Wnonnull-4.c for 32-bit targets (and 64-bit targets testing with a "-m32" option) after your r14-5115-g6e9ee44d96e5. It's logged as PR112419. brgds, H-P
