| | | | | | | | | | | | | | | | | | "$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

It is better for code size (and presumably efficiency) to use: movl $foo, %eax rather than: leal foo, eax Both give a nice zero extending "move immediate" instruction, the former is just smaller.

* Fix PR4533, which is about buggy codegen in x86-64 -static mode.Chris Lattner2009-07-111-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Basically, using: lea symbol(%rip), %rax is not valid in -static mode, because the current RIP may not be within 32-bits of "symbol" when an app is built partially pic and partially static. The fix for this is to compile it to: lea symbol, %rax It would be better to codegen this as: movq $symbol, %rax but that will come next. The hard part of fixing this bug was fixing abi-isel, which was actively testing for the wrong behavior. Also, the RUN lines are completely impossible to understand what they are testing. To help with this, convert the -static x86-64 codegen tests to use filecheck. This is much more stable and makes it more clear what the codegen is expected to be. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@75382 91177308-0d34-0410-b5e6-96231b3b80d8
