2012-11-01Revert the majority of the next patch in the address space series:Chandler Carruth
r165941: Resubmit the changes to llvm core to update the functions to support different pointer sizes on a per address space basis. Despite this commit log, this change primarily changed stuff outside of VMCore, and those changes do not carry any tests for correctness (or even plausibility), and we have consistently found questionable or flat out incorrect cases in these changes. Most of them are probably correct, but we need to devise a system that makes it more clear when we have handled the address space concerns correctly, and ideally each pass that gets updated would receive an accompanying test case that exercises that pass specificaly w.r.t. alternate address spaces. However, from this commit, I have retained the new C API entry points. Those were an orthogonal change that probably should have been split apart, but they seem entirely good. In several places the changes were very obvious cleanups with no actual multiple address space code added; these I have not reverted when I spotted them. In a few other places there were merge conflicts due to a cleaner solution being implemented later, often not using address spaces at all. In those cases, I've preserved the new code which isn't address space dependent. This is part of my ongoing effort to clean out the partial address space code which carries high risk and low test coverage, and not likely to be finished before the 3.2 release looms closer. Duncan and I would both like to see the above issues addressed before we return to these changes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@167222 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-19Move the support for using .init_array from ARM to the genericRafael Espindola
TargetLoweringObjectFileELF. Use this to support it on X86. Unlike ARM, on X86 it is not easy to find out if .init_array should be used or not, so the decision is made via TargetOptions and defaults to off. Add a command line option to llc that enables it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158692 91177308-0d34-0410-b5e6-96231b3b80d8

2012-02-15Modify the code that emits the module flags to use the new module flags accessorBill Wendling
method. This allows the target lowering code to not have to deal with MDNodes. Also, avoid leaking memory like a sieve by not creating a global variable for the image info section, but just emitting the code directly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@150624 91177308-0d34-0410-b5e6-96231b3b80d8

2011-05-05Remove a flag that would set the ".eh" symbol as .globl. MachO was the only oneBill Wendling
who used this flag, and it now emits CFI and doesn't emit this anymore. All other targets left this flag "false". <rdar://problem/8486371> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130918 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-27Rename getPersonalityPICSymbol to getCFIPersonalitySymbol, document it, andRafael Espindola
give it a bit more responsibility. Also implement it for MachO. If hacked to use cfi, 32 bit MachO will produce .cfi_personality 155, L___gxx_personality_v0$non_lazy_ptr and 64 bit will produce .cfi_presonality ___gxx_personality_v0 The general idea is that .cfi_personality gets passed the final symbol. It is up to codegen to produce it if using indirect representation (like 32 bit MachO), but it is up to MC to decide which relocations to create. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130341 91177308-0d34-0410-b5e6-96231b3b80d8
