| 22 | # Generate CGEN opcode files: arch-desc.[ch], arch-opc.[ch], |
| 23 | # arch-asm.c, arch-dis.c, arch-opinst.c, arch-ibld.[ch]. |
| 24 | # |
| 25 | # Usage: |
| 26 | # cgen.sh action srcdir cgen cgendir cgenflags arch prefix \ |
| 27 | # arch-file opc-file options [extrafiles] |
| 28 | # |
| 29 | # ACTION is currently always "opcodes". It exists to be consistent with the |
| 30 | # simulator. |
| 31 | # ARCH is the name of the architecture. |
| 32 | # It is substituted into @arch@ and @ARCH@ in the generated files. |
| 33 | # PREFIX is both the generated file prefix and is substituted into |
| 34 | # @prefix@ in the generated files. |
| 35 | # ARCH-FILE is the name of the .cpu file (including path). |
| 36 | # OPC-FILE is the name of the .opc file (including path). |
| 37 | # OPTIONS is comma separated list of options (???). |
| 38 | # EXTRAFILES is a space separated list (1 arg still) of extra files to build: |
| 39 | # - opinst - arch-opinst.c is being made, causes semantic analysis |
| 40 | # |
| 41 | # We store the generated files in the source directory until we decide to |
| 42 | # ship a Scheme interpreter (or other implementation) with gdb/binutils. |
| 43 | # Maybe we never will. |
| 44 | |
| 45 | # We want to behave like make, any error forces us to stop. |
