Ok to commit? It survived both a cris-elf regtest and a x86_64-linux-gnu native regtest. :)
---- 8< ---- The debug-function in sel-sched-dump.cc that would be suitable for a hookup to a command in gdb is guarded by #ifdef INSN_SCHEDULING, thus can't be used for all targets. Better move the function marked DEBUG_FUNCTION elsewhere, here to a file with a suitable static function to call. There are multiple sets of similar functions dumping HARD_REG_SETs, but cleaning that up is better left to a separate commit. gcc: * gdbinit.in (phrs): New command. * sel-sched-dump.cc (debug_hard_reg_set): Remove debug-function. * ira-color.cc (debug_hard_reg_set): New, calling print_hard_reg_set. --- gcc/gdbinit.in | 12 ++++++++++++ gcc/ira-color.cc | 7 +++++++ gcc/sel-sched-dump.cc | 10 ---------- 3 files changed, 19 insertions(+), 10 deletions(-) diff --git a/gcc/gdbinit.in b/gcc/gdbinit.in index 1f7592b0e26a..a76079a46af7 100644 --- a/gcc/gdbinit.in +++ b/gcc/gdbinit.in @@ -31,6 +31,7 @@ GCC gdbinit file introduces several debugging shorthands: pdd [dw_die_ref], pbm [bitmap], pel [location_t], + phrs [HARD_REG_SET] pp, pbs, pcfun They are generally implemented by calling a function that prints to stderr, @@ -145,6 +146,17 @@ Print given GENERIC expression in C syntax.
