--- Begin Message ---Package: gcc Version: 1:2.95.2-20 Severity: wishlist If I did a memcmp() on two 32-bit objects and used the result value as a boolean, then memcmp() should not go to the trouble of determining the order of those two objects. It should simply determine whether they're equal or not. This can be generalised to objects of any size. For example, the code int main() { return !memcmp("abcd", "efgh", 4); } produces the assembly (-S -g -O2), movl $.LC1,%esi movl $.LC0,%edi movl $4,%ecx cld testb $0,%al repz cmpsb sete %al which is a waste because it could've simply loaded the two objects into registers and compared them. The same is true on other architectures as well. I have reproduced this problem with gcc 2.95.3. -- System Information Debian Release: testing/unstable Kernel Version: Linux gondor 2.2.17 #1 Mon Sep 11 22:22:16 EST 2000 i586 unknown Versions of the packages gcc depends on: ii binutils 2.10.1.0.2-1 The GNU assembler, linker and binary utiliti ii cpp 2.95.2-20 The GNU C preprocessor. ii libc6 2.2.1-1 GNU C Library: Shared libraries and Timezone
