- Subject: ldreqd instruction in xscale
Hi,
I used the -march=armv4t with both the arm-elf-gcc compiler and xscale-elf-gcc
compiler. But xscale-elf-gcc generates different code. The ldreqd instruction
is used code generated by xscale-elf-gcc bt is absent in code generated by
arm-elf-gcc. Doesn't -march=armv4t specify the instruction to be used? I also
checked the arm architecture reference manual for this instruction but the
opcode for this instruction does not match any ldr instructions there.
What am I missing?
