I am working on implementing a new target for llvm. So far (to make debugging easier), I was compiling a C code into 2 steps: 1) generate the llvm file: clang -ccc-host-triple mytarget -emit-llvm -S myfile.c -o myfile.ll 2) generate the assembly file using llc -march=mytarget myfile.ll Sometimes, I add some verbosity for the 2nd command like "-print-after-all". Now, I'd like to compile a C code in 1 step using clang (clang -ccc-host-triple mytarge -S myfile.c -o...

I want to locate the module in llc that produces the assembler location control directives which are seen in the .s output file, so that I can modify it. I suspect these are not target-specific, and therefore are probably not in ./src/lib/Target/[mytarg], but I may be wrong. I'm fairly new to all this, so any pointers as to where I should be looking help a great deal. As an example, the current .s file generated by my target has directives such as .align, .rdata and .text (among others). I want to suppress certain ones which are incompatibl...
