Subject: [PowerPC] Replace cntlz[.] with cntlzw[.]
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=e60bc4e8b82e5ab94eb70bb21d94c431be9f257d;hp=e60bc4e8b82e5ab94eb70bb21d94c431be9f257d

[PowerPC] Replace cntlz[.] with cntlzw[.]

cntlz is the old POWER mnemonic. cntlzw is the PowerPC mnemonic.

This change fixes an issue when -no-integrated-as: The opcode cntlz is
unrecognized by gas

Alias the POWER mnemonic cntlz[.] to the PowerPC mnemonic cntlzw[.]
This is done for because the POWER cntlz mnemonic has be used by LLVM for
a very long time. We need to make sure that assembly programs
that are using the cntlz[.] do not break with this change.

Change PowerPC tests to reflect the insn change from cntlz to cntlzw.
Add assembly test to verify cntlz[.] is encoded correctly.
