So with brand new tuplified world, we need new statistics ;)
After parsing we are still the same:
cfg.c:216 (connect_src) 608608: 0.2%520:
0.0%3028808: 1.6% 519680:

Memory footprint in TOP is about 430MB (64bit machine).
On current mainline we need 191MB before IPA. Top consumers

Mainline with release checking uses 520MB ram again on the testcase with -O0
on x86_64 and 650MB with -O2. time-report with -O2 shows
df live regs : 4.84 ( 5%) usr 0.06 ( 1%) sys 4.76 ( 5%) wall

Hmm OVERLOAD tree takes 3% of the Garbage which seems like too big, though

I've been looking at a bunch of C++ codes, 16 or 32 seems like
a reasonable value for CP_LEXER_BUFFER_SIZE.

(In reply to comment #36)
The initial CP lexer bugger size is 1:
The same amount of garbage is also done for PR 8361.
Also note I could not compile this source again becuase of the use of long

The initial CP lexer bugger size is 1:
#define CP_LEXER_BUFFER_SIZE 1
That came in with the lex-all-ahead patch from Matt and Zack,
on 2004-09-20 (parser.c rev. 1.250 for the CVS history diggers)

Bug 12850 depends on bug 18683, which changed state.

Here are the results for -O0, now that PR 18683 is now fixed:
cp/lex.c:716 (copy_decl)1087604: 0.3% 0:
0.0%5906492:10.6% 0: 0.0%

On the mainline at -O1 (since I cannot compile at -O0 but that is a different
bug which I already filed):
cp/lex.c:716 (copy_decl) 910284: 0.1% 0:
0.0%
--- Additional Comments From pinskia at gcc dot gnu dot org 2004-12-03

I should note that 4.0.0 is like 3x faster than 3.3.2 at -O1 on this test.
