[llvm-commits] [PATCH] CallSite simplification

[Gabor Greif]

Hi all!

Attached patch simplifies (and hopefully speeds up)
the handling of call/invoke instructions by means of
the CallSite helper.

How it works:
The 'Call'-ness of the instruction is now tracked in a
flag, and there is no need to consult the instruction's
opcode. This saves a memory access at the cost of some
untagging operations.

I did not do performance testing, though I expect a small
speed advantage.

Also I did not care about formatting, will do later, when
folks think this can go into the tree. (80-col, trailing space...)

Any comments?

Cheers,

	Gabor
