[llvm-gcc] Using __asm__ to rename symbols is broken on OS/X
Last modified: 2010-02-22 12:50:21 CST
LLVM miscompiles this: void foo() __asm__("_foo2"); void bar() { foo(); } "_" (aka USER_LABEL_PREFIX in GCC target header files) should only be added to *user* symbols, not to __asm__'s. Because of this, the "foo" function should really reference "_foo2", not "__foo2". The right way to do this is to remove the "_" prefixification from the darwin asm printer, and make the CFE add USER_LABEL_PREFIX to user labels (duh), but not asm labels. -Chris
