macos: Fix asm-c-connect-test via some heavy-handed hackery in the ASM symbol handling in case C symbols get a leading underscore (but ASM symbols do not). But this is now like clang and GCC on Darwin work: asm symbols are undecorated, C symbols get a _ prepended, so to connect both some trickery is involved for the ASM symbols that don't have a _ prepended. They must be included in the C symbol table (because that's what we use to lookup also ASM labels), but they also must not disturb the normal C symbol (which don't have the _ prepended), so they need some mangling. A bit unsatisfying, but well. So, add asm-c-connect-test to the working ones for Darwin as well. 2020-05-23 09:46:32 +08:00			`#ifdef __APPLE__`

Fix some code suppression fallout Some more subtle issues with code suppression: - outputting asms but not their operand setup is broken - but global asms must always be output - statement expressions are transparent to code suppression - vtop can't be transformed from VT_CMP/VT_JMP when nocode_wanted Also remove .exe files from tests2 if they don't fail. 2016-12-20 11:49:22 +08:00			`extern int printf (const char *, ...);`
__asm__() outside function gcc/pcc allow __asm__() outside a function body: extern void vide(void); __asm__("vide: ret"); There is many such code in the Linux kernels. 2016-05-02 03:38:38 +08:00			`extern void vide(void);`
