Hi, I have added the new instruction in opcode and invoked it using asm_volatile .The new instruction is generated in the object dump. Now I wrote an RTL template for the same instruction in a .md file and some cost value calculation in cfile.Then I run the sample c code that invokes the instruction defined in .md file. I examined the files generated in -fdump-rtl-all. But the added instruction is not generated . *How can I add comments to files generated in rtl dump?* I have added fprintf (dump_file, "Test hello world\n"); to *gcc/cfgrtl.cc *and observed *.expand file .But I could not find the test word in that file .
