* [X86] Add a new LOW32_ADDR_ACCESS_RBP register class.Quentin Colombet2016-05-063-4/+17
| | | | | | | | ABIs like NaCl uses 32-bit addresses but have 64-bit frame. The new register class reflects those constraints when choosing a register class for a address access. llvm-svn: 268796

| | | | | | | | This register class may be used by any ABIs that uses x86_64 ISA while using 32-bit addresses, not just in X32 cases. Make sure the name reflects that. llvm-svn: 268795

| | | | | | | | | | | | When inferring availability attributes for tvos, watchos from ios, we use the same source location and set the implicit bit to true. So when emitting diagnostics on inferred attributes, we have a source location. rdar://25893544 llvm-svn: 268793

As the caller is the one that needs to add the name of where the "object file" comes from to the error message as the object file could be in an archive, or coming from a slice of a Mach-O universal file or a buffer created by a JIT. In the cases of a Mach-O universal file the architecture name may or may not also need to be printed which is up to the tool code. For example if the tool code is only selecting the host architecture slice then that architecture name is never printed. This patch is the change to the libObject code and there will be follow on commits for changes to the code for each tool. llvm-svn: 268789

* Refactor the Verifier so it can diagnose IR validation errors and debugAdrian Prantl2016-05-061-159/+195
| | | | | | | | | | | | | | | | | | | | | | | info metadata errors separately. (NFC) This patch refactors the Verifier so it can diagnose IR validation errors and debug info metadata errors separately. The motivation behind this change is that broken (or outdated) debug info can be "recovered" from by stripping the debug info. The problem I'm trying to solve with this sequence of patches is that historically we've done a really bad job at verifying debug info. We want to be able to make the verifier stricter without having to worry about breaking bitcode compatibility with existing producers. For example, we don't necessarily want IR produced by an older version of clang to be rejected by an LTO link just because of malformed debug info, and rather provide an option to strip it. Note that merely outdated (but well-formed) debug info would continue to be auto-upgraded in this scenario. http://reviews.llvm.org/D19986 rdar://problem/25818489 llvm-svn: 268778
* Frontend: support -I=path for sysroot expansionSaleem Abdulrasool2016-05-062-2/+42
| | | | | | | | | | | | | | | | | | From the GCC manpage: -I dir ... If dir begins with =, then the = will be replaced by the sysroot prefix; see --sysroot and -isysroot. Add support to expand the `=` as a prefix of the include path with the sysroot if specified. `-isysroot` takes precedence over `--sysroot` as the normal argument behaviour occurs. The ordering of the `-isysroot` is relevant to the path substituted. If no `--sysroot=` or `-isysroot` option is present, the = is not expanded. Resolves PR26965! llvm-svn: 268777
* [Hexagon] Be careful about anti-dependencies with a call in packetizerKrzysztof Parzyszek2016-05-061-2/+24
| | | | | | | | | | | In a case like J2_callr <ga:@foo>, %R0<imp-use>, ... R0<def> = ... the anti-dependency on R0 cannot be ignored and the two instructions cannot be packetized together, since if they were, the assignment to R0 would take place before the call. llvm-svn: 268776
* [GVN] Handle unordered atomics in cross block FREPhilip Reames2016-05-062-5/+60
| | | | | | You'll note there are essentially no code changes here. Cross block FRE heavily reuses code from the block local FRE. All of the tricky parts were done as part of the previous patch and the refactoring that removed the original code duplication. llvm-svn: 268775

* [GVN] Do local FRE for unordered atomic loadsPhilip Reames2016-05-062-4/+251
| | | | | | | | | | This patch is the first in a small series teaching GVN to optimize unordered loads aggressively. This change just handles block local FRE because that's the simplest thing which lets me test MDA, and the AvailableValue pieces. Somewhat suprisingly, MDA appears fine and only a couple of small changes are needed in GVN. Once this is in, I'll tackle non-local FRE and PRE. The former looks like a natural extension of this, the later will require a couple of minor changes. Differential Revision: http://reviews.llvm.org/D19440 llvm-svn: 268770
* Tweak the ThinLTO pass pipelineMehdi Amini2016-05-061-17/+7
| | | | | | | | | | | | | | | | | | | | | Summary: The original ThinLTO pipeline was derived from some work I did tuning FullLTO on the test suite and SPEC. This patch reduces the amount of work done in the "linker phase" of the build, and extend the function simplifications passes performed during the "compile phase". This helps the build time by reducing the IR as much as possible during the compile phase and limiting the work to be performed during the "link phase", while keeping the performance "on par" with the existing pipeline.

* [AMDGPU][llvm-mc] Add support for sendmsg(...) syntax.Artem Tamazov2016-05-0610-36/+559
| | | | | | | | | | | | | | | | | | | Added support for sendmsg(MSG[, OP[, STREAM_ID]]) syntax in s_sendmsg and s_sendmsghalt instructions. The syntax matches the SP3 assembler/disassembler rules. That is why implicit inputs (like M0 and EXEC) are not printed to disassembly output anymore. sendmsg(...) allows only known message types and attributes, even if literals are used instead of symbolic names. However, raw literal (without "sendmsg") still can be used, and that allows for any 16-bit value. Tests updated/added. Differential Revision: http://reviews.llvm.org/D19596 llvm-svn: 268762

* [AArch64] Combine callee-save and local stack SP adjustment instructions.Geoff Berry2016-05-0617-167/+289
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: If a function needs to allocate both callee-save stack memory and local stack memory, we currently decrement/increment the SP in two steps: first for the callee-save area, and then for the local stack area. This changes the code to allocate them both at once at the very beginning/end of the function. This has two benefits: 1) there is one fewer sub/add micro-op in the prologue/epilogue 2) the stack adjustment instructions act as a scheduling barrier, so moving them to the very beginning/end of the function increases post-RA scheduler's ability to move instructions (that only depend on argument registers) before any of the callee-save stores This change can cause an increase in instructions if the original local stack SP decrement could be folded into the first store to the stack. This occurs when the first local stack store is to stack offset 0. In this case we are trading off one more sub instruction for one fewer sub micro-op (along with benefits (2) and (3) above).
