Which part of the generated code do you think is not correct? Could you be more specific? I compiled this program with clang and ran it on a mips board. It returns the expected result (21).

I check the Mips backend for the following C code fragment compile result. It seems not correct. Is it my misunderstand or it's a bug. //ch8_3.cpp #include <stdarg.h> int sum_i(int amount, ...) { int i = 0; int val = 0; int sum = 0; va_list vl; va_start(vl, amount); for (i = 0; i < amount; i++) { val = va_arg(vl, int); sum += val; } va_end(vl);

Hi, In order to emit "la $4,ADDR" instead of lui followed by addiu to load the data address, could you advise what is proper way to revise td files in the MIPS target?

I need to be able to emit .globl for the soft float routines used by mips16. The routines are called but there is no .globl definition for them. How can I do this? Background: I have a strange issue that I encountered with mips16 hard float. Part of mips16 hard float is to emit calls to runtime routines with the same signature as usual soft float routines, except that they are implemented

Hi, MIPS LA25 thunk is used to call PIC function from non-PIC code. Usually it contains three instructions: lui $25, %hi(func) addiu $25, $25, %lo(func) j func We can write such thunk in an arbitrary place of the generated file. But if a PIC function requires the thunk is the first routine in a section, we can optimize the code and escape jump instruction. To do so we just write the following thunk right before the PIC rout...
