- Subject: GAS ARM config/tc-arm.c
I am currently working on a research project that includes adding a new
instruction to the ARM architecture. I've found the places that I need
to modify, but I'm not sure what the exact format of the code in GAS
needs to be. Specifically, I'm looking at the config/tc-arm.c file and
the following lines:
#define T16_32_TAB \
[...]
X(ldr, 6800, f8500000), \
and
tCE(ldr, 4100000, ldr, 2, (RR, ADDR), ldst, t_ldst),
Can someone provide me with a description of how the numbers 6800,
f8500000, and 4100000 are derived? I'm digging through the ARM
reference manual, but would greatly appreciate a hint regarding what I'm
looking at.
Thanks,
Michael Kirkpatrick
