[LLVMdev] cortex-m{3,4} special registers
Hi Kurt,
The assembly parser doesn't (yet) handle these, you're right. Currently, the MRS instruction is split into two variants in the ARMInstrThumb2.td file, t2MRS and t2MRSsys, one for the user mode version reading cpsr and one for the system mode version reading spsr. MSR, by contrast, has a custom parse method for the mask operand since it's a bit more complex than an either/or.
You'll likely want to merge the two MRS variants into one and add an...

[LLVMdev] cortex-m{3,4} special registers
