* Return ErrorOr from getSection.Rafael Espindola2015-07-019-75/+144
| | | | | | | | | | | | | | This also improves the logic of what is an error: * getSection(uint_32): only return an error if the index is out of bounds. The index 0 corresponds to a perfectly valid entry. * getSection(Elf_Sym): Returns null for symbols that normally don't have sections and error for out of bound indexes. In many places this just moves the report_fatal_error up the stack, but those can then be fixed in smaller patches. llvm-svn: 241156

* [X86] Avoid over-relaxation of 8-bit immediates in integer arithmetic ↵Michael Kuperstein2015-07-013-24/+200
| | | | | | | | | | | | | | | | | | instructions. Only consider an instruction a candidate for relaxation if the last operand of the instruction is an expression. We previously checked whether any operand is an expression, which is useless, since for all instructions concerned, the only operand that may be affected by relaxation is the last one. In addition, this removes the check for having RIP as an argument, since it was plain wrong - even when one of the arguments is RIP, relaxation may still be needed. This fixes PR9807.

* [LoopUnroll] Use undef for phis with no value liveDavid Majnemer2015-07-012-1/+25
| | | | | | | | We would create a phi node with a zero initialized operand instead of undef in the case where no value was originally available. This was problematic for x86_mmx which has no null value. llvm-svn: 241143
* [SCCP] Turn loads of null into undef instead of zero initialized valuesDavid Majnemer2015-07-012-1/+6
| | | | | | | | | | Surprisingly, this is a correctness issue: the mmx type exists for calling convention purposes, LLVM doesn't have a zero representation for them. This partially fixes PR23999. llvm-svn: 241142
* [NaryReassociate] enhances nsw by leveraging @llvm.assumeJingyue Wu2015-07-012-14/+91
| | | | | | | | | | | | | | | | | | | | | Summary: nsw are flaky and can often be removed by optimizations. This patch enhances nsw by leveraging @llvm.assume in the IR. Specifically, NaryReassociate now understands that assume(a + b >= 0) && assume(a >= 0) ==> a +nsw b As a result, it can split more sext(a + b) into sext(a) + sext(b) for CSE.

* [SEH] Add new intrinsics for recovering and restoring parent framesReid Kleckner2015-06-307-82/+169
| | | | | | | | | | | | | | | | | | | | | | | | | The incoming EBP value established by the runtime is actually a pointer to the end of the EH registration object, and not the true parent function frame pointer. Clang doesn't need llvm.x86.seh.exceptioninfo anymore because we know that the exception info pointer is at a fixed offset from this incoming EBP. The llvm.x86.seh.recoverfp intrinsic takes an EBP value provided by the EH runtime and returns a pointer that is usable with llvm.framerecover. The llvm.x86.seh.restoreframe intrinsic is inserted by the 32-bit specific preparation pass in blocks targetted by the EH runtime. It re-establishes any physical registers used by the parent function to address the stack, such as the frame, base, and stack pointers. Neither of these intrinsics correctly handle stack realignment prologues yet, but it's possible to add that later.

* [FaultMaps] Let the frontend pre-select implicit null check candidates.Sanjoy Das2015-06-304-6/+62
| | | | | | | | | | | | | | | | | | Summary: This change introduces a !make.implicit metadata that allows the frontend to pre-select the set of explicit null checks that will be considered for transformation into implicit null checks. The reason for not using profiling data instead of !make.implicit is explained in the change to `FaultMaps.rst`.

* Pack MCSymbol::HasName in to a spare bit in the section/fragment union.Pete Cooper2015-06-302-19/+23
| | | | | | | | | | | | This is part of an effort to pack the average MCSymbol down to 24 bytes. The HasName bit was pushing the size of the bitfield over to another word, so this change uses a PointerIntPair to fit in it to unused bits of a PointerUnion.

* COFF: Do not assign linker-weak symbols to selectany comdat sections.Peter Collingbourne2015-06-303-5/+14
| | | | | | | | | | | | | | It is mandatory to specify a comdat in order to receive comdat semantics for a symbol. We were previously getting this wrong in -function-sections mode; linker-weak symbols were being emitted in a selectany comdat. This change causes such symbols to use a noduplicates comdat instead, fixing the inconsistency. Also correct an inaccuracy in the docs.

* [DebugInfo] Let IRBuilder::SetInsertPoint(BB::iterator) update current debug ↵Alexey Samsonov2015-06-302-2/+33
| | | | | | | | | | | | | | | | | | | | | | | | | | | location. IRBuilder::SetInsertPoint(BB, BB::iterator) is an older version of IRBuilder::SetInsertPoint(Instruction). However, the latter updates the current debug location of emitted instruction, while the former doesn't, which is confusing. Unify the behavior of these methods: now they both set current debug location to the debug location of instruction at insertion point. The callers of IRBuilder::SetInsertPoint(BB, BB::iterator) doesn't seem to depend on the old behavior (keeping the original debug info location). On the contrary, sometimes they (e.g. SCEV) *should* be updating debug info location, but don't. I'll look at gdb bots after the commit to check that we don't regress on debug info somewhere. This change may make line table more fine-grained, thus increasing debug info size. I haven't observed significant increase, though: it varies from negligible to 0.3% on several binaries and self-hosted Clang. This is yet another change targeted at resolving PR23837. llvm-svn: 241101

Previously the generated CMake files contained hardcoded paths which prevented a binary installation from being relocated to a different place in the file system. This problem was most noticeable in LLVM's official binary releases which were completely unusable by a downstream project trying to import the CMake targets. Package maintainers who choose to modify the install location of the CMake directory without using the ``PROJ_cmake`` Makefile variable override will need to patch the generated``LLVMConfig.cmake`` so that ``LLVM_INSTALL_PREFIX`` and ``_LLVM_CMAKE_DIR`` variables are set correctly. llvm-svn: 241080
