llvm dev - Dec 2010 - [LLVMdev] asm-verbose (on by default) is really, really slow

Very true, but we do want the testsuite to run fast.  Can it be sped up?

Can't we just run testsuite with asm-verbose=0 ?

That is already the default. From test-suite/Makefile.programs:

# Disable asm-verbose.  This can slow down compilation and is not what the
# compilers default to using.
LLCFLAGS += -asm-verbose=false

Most (new) nightly testers run TEST=simple which doesn't invoke llc at all.

I meant llvm/test.  I'm just surprised it is that slow, what is costing all
the time?

No.  There are tests that look for line numbers, for example.
