With this patch, "insn" and "curr_insn" as used from C++ fragments in .md
files are strengthened from rtx to rtx_insn *, allowing numerous
target-specific functions to have their params be similiar strengthened.
The top-level interfaces ("recog", "split", "peephole2") continue to take
a plain rtx for "insn", to avoid introducing dependencies on other
patches.
gcc/
* recog.h (insn_output_fn): Update this function typedef to match
the changes below to the generated output functions, strengthening
the 2nd param from rtx to rtx_insn *.
* final.c (get_insn_template): Add a checked cast to rtx_insn * on
insn when invoking an output function, to match the new signature
of insn_output_fn with a stronger second param.
* genconditions.c (write_header): In the generated code for
gencondmd.c, strengthen the global "insn" from rtx to rtx_insn *
to match the other changes in this patch.
* genemit.c (gen_split): Strengthen the 1st param "curr_insn" of
the generated "gen_" functions from rtx to rtx_insn * within their
implementations.
* genrecog.c (write_subroutine): Strengthen the 2nd param "insn" of
the subfunctions within the generated "recog_", "split", "peephole2"
function trees from rtx to rtx_insn *. For now, the top-level
generated functions ("recog", "split", "peephole2") continue to
take a plain rtx for "insn", to avoid introducing dependencies on
other patches. Rename this 2nd param from "insn" to
"uncast_insn", and reintroduce "insn" as a local variable of type
rtx_insn *, initialized at the top of the generated function with
a checked cast on "uncast_insn".
(make_insn_sequence): Strengthen the 1st param "curr_insn" of
the generated "gen_" functions from rtx to rtx_insn * within their
prototypes.
* genoutput.c (process_template): Strengthen the 2nd param within
the generated "output_" functions "insn" from rtx to rtx_insn *.
