--- Comment #13 from Loria <Loria at phantasia dot org> --- <QUOTE https://llvm.org/bugs/show_bug.cgi?id=26344 <> $ clang -fsanitize=undefined test.c -o test && ./test test.c:11:13: runtime error: shift exponent 32 is too large for 32-bit type 'unsigned int' 0xA7 0xA7 0x1 0x1 0x0 0x0 line 11 has: if((a = rotate_left (val, i)) <= 0xFF) expands to: if((a = (val << i | val >> (32 - i))) <= 0xFF) when i == 0, we will compute: if((a = (val << 0 | val >> (32 - 0))) <= 0xFF) val >> 32 is undefined behavior. </QUOTE> I am unsure if that is correct, since I never experienced on any machine any problem doing >>32 (resulted in 0 as expected on all machines i did it) -- You are receiving this mail because: You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
