Subject: GCC ASM(): Urgent!
Date: Tue, 29 Feb 2000 18:10:00 -0000 [thread overview]
Message-ID: <38BC7BDD.8C3DFF6C@telecruz.com> (raw)
Hi,
I'm using GNU CC, ccmips or asmips. I see within the generated .s file
from .c file there are:
jpeg_idct_ifast:
.frame $fp,368,$31 # vars= 360, regs= 1/0, args= 0, extra= 0
.mask 0x40000000,-8
.fmask 0x00000000,0
1. What does .frame,.mask and .fmask means?
2. Which registers are protected? Which registers I can use in my ASM()
routine?
3. How to support Mips R3900 instruction like MULT rd,rs,rt?
4. In GCC book within a macro "\" gives operator value, but the example
gives compile error:
.macro mname rd
.word \ rd
.endm
5. How to debug and trace in the asm() instructions in a .C file?
Many thanks!
