If you read the whole thread, LLVM needs a rewritten exception handling as
well. Further, a quick test
of table based exception handling on bansi1 (which is mainly a memory manager
test) gives:
standard exception handling:
fpctrunk\tests\bench>pp11 bansi1 -O3
fpctrunk\tests\bench>bansi1
Test 1: 1000000 done in 0.537 sec
Test 2: 1000000 done in 0.535 sec
Test 3: 1000000 done in 0.587 sec
SEH based exception handling:
fpctrunk\tests\bench>pp11 bansi1 -O3
fpctrunk\tests\bench>bansi1
Test 1: 1000000 done in 0.456 sec
Test 2: 1000000 done in 0.457 sec
Test 3: 1000000 done in 0.446 sec
Florian, I am not sure what this is supposed to prove ?
It's 15% off the elapsed time (almost 1/6th), that seems worth spending some
time on...
