* Reapply my previous asmprinter changes now with more testing and two Chris Lattner2009-07-142-7/+5
| | | | | | | | | | | | | | | | | | | | | | additional bug fixes: 1. The bug that everyone hit was a problem in the asmprinter where it would remove $stub but keep the L prefix on a name when emitting the indirect symbol. This is easy to fix by keeping the name of the stub and the name of the symbol in a StringMap instead of just keeping a StringSet and trying to reconstruct it late. 2. There was a problem printing the personality function. The current logic to print out the personality function from the DWARF information is a bit of a cesspool right now that duplicates a bunch of other logic in the asm printer. The short version of it is that it depends on emitting both the L and _ prefix for symbols (at least on darwin) and until I can untangle it, it is best to switch the mangler back to emitting both prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75646 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | "$non_lazy_ptr" to symbols instead of doing it with "printSuffixedName". This gets us to the point where there is a real separation between computing a symbol name and printing it, something I need for MC printer stuff. This patch also fixes a corner case bug where unnamed private globals wouldn't get the private label prefix. Next up, rename all uses of getValueName -> getMangledName for better greppability, and then tackle the ppc/arm backends to eliminate "printSuffixedName". git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75610 91177308-0d34-0410-b5e6-96231b3b80d8
* Change the internal interface to makeNameProper to take a bool thatChris Lattner2009-07-142-8/+8
| | | | | | | | | | | | | | indicates whether the label is private or not, instead of taking prefix stuff. One effect of this is that symbols will be generated with *just* the private prefix, instead of both the private prefix *and* the user-label-prefix, but this doesn't matter as long as it is consistent. For example we'll now get "Lfoo" instead of "L_foo". These are just assembler temporary labels anyway, so they never even make it into the .o file. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75607 91177308-0d34-0410-b5e6-96231b3b80d8
