Rename temporary symbols if they conflict with artificial symbols created by the assembler. This was blocking parsing any large .s produced by clang for example. Fixes PR8596. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120603 91177308-0d34-0410-b5e6-96231b3b80d8 2010-12-01 20:46:11 +00:00			`// RUN: llvm-mc -triple i386-unknown-unknown %s \| FileCheck %s`

Don't store Twine temporaries, it's not safe. And don't append the name over and over again in the loop. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@129210 91177308-0d34-0410-b5e6-96231b3b80d8 2011-04-09 11:26:27 +00:00			`.Ltmp01:`

Centralize the handling of unique ids for temporary labels. Before this patch code wanting to create temporary labels for a given entity (function, cu, exception range, etc) had to keep its own counter to have stable symbol names. createTempSymbol would still add a suffix to make sure a new symbol was always returned, but it kept a single counter. Because of that, if we were to use just createTempSymbol("cu_begin"), the label could change from cu_begin42 to cu_begin43 because some other code started using temporary labels. Simplify this by just keeping one counter per prefix and removing the various specialized counters. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232535 91177308-0d34-0410-b5e6-96231b3b80d8 2015-03-17 20:07:06 +00:00			`// CHECK: .Ltmp00`
