Looks like I managed to confuse myself even more (too many variants of
gen.pl :-(
Above results are for a simplified test case (gen-20090720.pl, attached).
Here are the timings I get using unpatched vs. patched GDB using the
original gen.pl from
http://sourceware.org/ml/gdb-patches/2009-07/msg00417/gen.pl
NNN before after
256 0m03.544s 0m02.724s
512 0m15.693s 0m10.025s
1024 1m06.844s 0m39.742s
So not such a drastic improvement for *this* test case.
Most of the time for this test is actually spent in dwarf2_frame_find_fde,
for which I'll send another patch shortly.
Thanks,
