[LLVMdev] Swapping function arguments in libcalls
...forgive me in that case. The idea is to basically commute/swap function arguments just like in instructions if it's beneficial, mainly for libcalls. Consider this example: typedef float t; t foo(t a, t b) { return a*b; } this gets compiled into (msp430 asm, arm does the same): call #__mulsf3 ret but if we instead do "return b*a;" we get: push.w r11 push.w r10 mov.w r14, r11 mov.w r15, r10 mov.w r13, r15 mov.w r12, r14 mov.w r10, r13 mov.w r11, r12 call #__mulsf3 pop.w r10 pop.w r11 ret Noti...

[LLVMdev] overriding InitLibcallNames?
...een mips16 and mips32 functions. This is how gcc mips16 works and there is already this kind of soft float library that is implemented as hard float mips32 functions. Basically it is soft float but with different library entry names. So for example, instead of Names[RTLIB::MUL_F32] = "__mulsf3"; I would want Names[RTLIB::MUL_F32] = "__mips16__mulsf3"; I'm trying to think of the best way to do this since soft float is not done in target independent code but this is a target dependent version of soft float. I'll need to override a whole set of names and mips 16 h...
