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);

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

...the `MipsTargetInfo`. Sure we can implement each of these methods somewhere in the `InputSectionBase` class under `if (MIPS)` statements. Any opinions about the best method / approach? == Q2 R_MIPS_HI16 and R_MIPS_LO16 relocations perform a special calculation if a target symbol's name is `_gp_disp` [2]. AFAIK now in the target `relocateOne` method there is no chance to get the traget symbol name. Is it okay to pass the target symbol index and provide `MipsTargetInfo` access to the symbol table of the processing input file?
