Tested code with: clang -fsanitize=address,undefined,nullability -pie -fPIE -Iinclude -I. -g tcc.c -o tcc.tcc -lm -ldl -lpthread ./tcc.tcc -Iinclude -I. -b -g tcc.c -o tcc.tcc1 -lm -ldl -lpthread Also checked on i386/x86_64 with -fsanitize=memory (others not supported). arm-link.c: use read32le/write32le/add32le to avoid unaligned access tcc.h i386-asm.c: fix signed left shift lib/bcheck.c: Add _Atomic libtcc.c: Correct MEM_DEBUG_CHECK3 to avoid unaligned access riscv64-link.c: Fix R_RISCV_SET16 tccpp.c: Align tal_header_t to avoid unaligned access tccgen.c x86_64-gen.c: avoid use of uninitialized value There are still warnings reported: tccgen.c:4031:13: runtime error: member access within null pointer of type 'TCCState' (aka 'struct TCCState') tccelf.c:321:22: runtime error: applying zero offset to null pointer tccelf.c:1132:23: runtime error: applying non-zero offset 169184 to null pointer A lot of left shift of negative value warnings. I ignored these for the moment. Also the -run option does no work well with -fsanitize. It gets confused because it does not detect that the generated code in memory is used without -fsanitize option. There are a lot more -fsanitize options. I did not find serious problems with them. |
