[Bug middle-end/37448] [4.3 Regression] gcc 4.3.1 cannot compile big function



------- Comment #18 from hubicka at gcc dot gnu dot org  2008-09-18 21:11 -------
Hi,
some stats on instruction counts and references Kenny asked about:

At -O2:
jh@gcc17:~/gcc-baseline/build-ada/prev-gcc$ grep "(insn"
e.i.157r.outof_cfglayout | wc -l
307811
jh@gcc17:~/gcc-baseline/build-ada/prev-gcc$ grep "(call_insn"
e.i.157r.outof_cfglayout | wc -l
157016
jh@gcc17:~/gcc-baseline/build-ada/prev-gcc$ grep "(jump_insn"
e.i.157r.outof_cfglayout | wc -l
18650

at -O0:
jh@gcc17:~/gcc-baseline/build-ada/prev-gcc/O0$ grep "(insn"
e.i.157r.outof_cfglayout | wc -l
411876
jh@gcc17:~/gcc-baseline/build-ada/prev-gcc/O0$ grep "(call_insn"
e.i.157r.outof_cfglayout | wc -l
166471
jh@gcc17:~/gcc-baseline/build-ada/prev-gcc/O0$ grep "(jump_insn"
e.i.157r.outof_cfglayout | wc -l
18218

I am not sure if I can grep for references in some of the RTL dumps...
