[Bug rtl-optimization/24760] -d option changes generated code



------- Comment #4 from amylaar at gcc dot gnu dot org  2005-11-09 19:35 -------
I have observed the -quiet influence only with a proprietary testcase so far
(EEMBC aiifft01/bmark.c for sh-elf -m4 -ml -g -O3 -version -fomit-frame-pointer
-funroll-loops --param max-inline-insns-single=50000).
Compiling with -da -quiet generally makes this code smaller than compiling with
-quiet only, but with a probability of about 1/5th -da -quiet produces larger
code.
-da without -quiet generally produces code that is larger than any of the above
scenarios, but sometimes it produces identical code to -quiet (without -da).
