Bug #: 55036
Summary: Compiler fails with message "internal compiler error:
in reg_save_code, at caller-save.c:158"
Classification: Unclassified
Product: gcc
Version: 4.6.3
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
AssignedTo: unassigned@gcc.gnu.org
ReportedBy: jantlatlik@gmail.com
Assume the movm insn is the first define_insn pattern in the target md file:
When compiling with the built compiler at least with optimization level 2
(-O2), the compiler will always fail during compile when function calls are
involved.
The following error message occurs:
"internal compiler error: in reg_save_code, at caller-save.c:158"
A short web search lead me to this:
http://old.nabble.com/upgrading-gcc-4.4.0-to-gcc-4.7.0%3Aconfigure%3A-error%3A-cannot-compute-suffix-of-object-files%3A-cannot-compile-td34003613.html
Apparently he could fix it by putting any other define_insn (e.g. nop) right
before the mov insns, so the first mov insn does not get the index 0.
That worked for me as well.
I could not find any documentation about not putting a mov insn pattern at the
beginning of the md file. Therefore I assume it's a bug.

Yes, it's a bug.
The various places in caller-save.c that test cached_reg_save_code[...] != 0
should be testing it >= 0. Same for cached_reg_restore_code[...].

* gensupport.c (init_rtx_reader_args_cb): Start counting code
generating patterns from 1 to free up 0 for CODE_FOR_nothing.
* gencodes.c (main): Give CODE_FOR_nothing the value 0. Add
the LAST_INSN_CODE marker at the end.
* genoutput.c (nothing): New static struct data.
(idata): Initialize to ¬hing.
(idata_end): Initialize to ¬hing.next.
(init_insn_for_nothing): New function to create dummy 'nothing' insn.
(main): Use it.
* genpeep.c (insn_code_number): Remove global variable.
(gen_peephole): Take it as an argument instead.
(main): Take insn_code_number from read_md_rtx.
* optabs.h: Revert r161809:
(optab_handlers): Change type of insn_code back to insn_code.
(optab_handler, widening_optab_handler, set_optab_handler,
set_widening_optab_handler, convert_optab_handler,
set_convert_optab_handler, direct_optab_handler,
set_direct_optab_handler): Remove int casts.
Revert to treating the insn_code field as "insn_code".
