* AMDGPU: Improve splitting 64-bit bit ops by constantsMatt Arsenault2016-09-1415-96/+614
| | | | | | | | This addresses a TODO to handle operations besides and. This also starts eliminating no-op operations with a constant that can emerge later. llvm-svn: 281488
* CodeGen: simplify the logic a slight bitSaleem Abdulrasool2016-09-143-14/+8
| | | | | | | | | Move the definition of `getTriple()` into the header. It would just call `getTarget().getTriple()`. Inline the definition to allow the compiler to see the same amount of the layout as previously. Remove the more verbose `getTarget().getTriple()` in favour of `getTriple()`. llvm-svn: 281487

* [LV] Process pointer IVs with PHINodes in collectLoopUniformsMatthew Simpson2016-09-142-4/+191
| | | | | | | | | | | | | | | This patch moves the processing of pointer induction variables in collectLoopUniforms from the consecutive pointer phase of the analysis to the phi node phase. Previously, if a pointer induction variable was used by both a scalarized non-memory instruction as well as a vectorized memory instruction, we would incorrectly identify the pointer as uniform. Pointer induction variables should be treated the same as other phi nodes. That is, they are uniform if all users of the induction variable and induction variable update are uniform.

* [ARM] Promote small global constants to constant poolsJames Molloy2016-09-145-1/+254
| | | | | | | | | | | | | | | | | | | | | | | | If a constant is unamed_addr and is only used within one function, we can save on the code size and runtime cost of an indirection by changing the global's storage to inside the constant pool. For example, instead of: ldr r0, .CPI0 bl printf bx lr .CPI0: &format_string format_string: .asciz "hello, world!\n" We can emit: adr r0, .CPI0 bl printf bx lr .CPI0: .asciz "hello, world!\n" This can cause significant code size savings when many small strings are used in one function (4 bytes per string). llvm-svn: 281484
* MCInstrDesc: this fixes an issue setting/getting member Flags, whichSjoerd Meijer2016-09-142-3/+3

| | | | | | | | | | | This patch corresponds to review: https://reviews.llvm.org/D24021 In the initial implementation of this instruction, I forgot to account for variable indices. This patch fixes PR30189 and should probably be merged into 3.9.1 (I'll open a bug according to the new instructions). llvm-svn: 281479

| | | | | | | | There is currently no codegen for Power9 that depends on the directive so this is NFC for now but will be important in the future. This was missed in r268950 so I'm adding it now. llvm-svn: 281473

* [OMPT] fix task frame information for gomp interfaceJonas Hahnfeld2016-09-144-52/+56
| | | | | | | | | | | Previous differencials D23305-D23310 changed task frame information management only for the kmp interface, but not for the whole gomp interface. This broke some testcases when building with gcc. This patch fixes the broken task frame information for the gomp interface. Patch by Joachim Protze!

* [OMPT] save exit address to lwt if availableJonas Hahnfeld2016-09-142-27/+22
| | | | | | | | | | | In case, the current team is a serialized team (lwt), the frame information should be written to this data structure. Before, nested serialized teams would overwrite the same task information. Patch by Joachim Protze! Differential Revision: https://reviews.llvm.org/D23310 llvm-svn: 281467
* [OMPT] fix __ompt_get_teaminfo to consult lwt entries of parent teamsJonas Hahnfeld2016-09-142-1/+317
| | | | | | | | | | | | | | | The comment already states, that this function should work similarly as __ompt_get_taskinfo. The function only looked for lwt entries of the current team, but not when unrolling the parents. This fix aligns the implementation to __ompt_get_taskinfo. The new test case creates a single theaded team (->lwt) and then a nested active team. Before the innermost print_id(1) would deliver a different team then the outer print_id(0).

* [OMPT] Reset task exit frame when execution is finishedJonas Hahnfeld2016-09-142-0/+14
| | | | | | | | | | | | | | | | The exit address is set when execution of a task is started and should be reset as soon as the execution is finished. Especially for the asm implementation of __kmp_invoke_microtask, resetting in this call would be painfull, so reset just after the invokation. The testcase shows the effect of this patch: Before, the implicit barriers at the end of an implicit task would see an exit address for the implicit task. This barrier is a task scheduling point. Thus, any explicit task scheduled there would see an exit, but no reenter address for the implicit task. Patch by Joachim Protze! Differential Revision: https://reviews.llvm.org/D23307 llvm-svn: 281465
* [OMPT] Align implementation of reenter frame address to latest (frozen) ↵Jonas Hahnfeld2016-09-146-34/+58
| | | | | | | | | | | | | | | | version of OMPT spec The latest OMPT spec changed the semantic of a tasks reenter frame to be the application frame, that will be entered, when the runtime frame drops. Before it was the last frame in the runtime. This doesn't work for some gcc execution pathes or even clang generated code for : Since there is no runtime frame between the executed task and the encountering task.

* [cmake] Support overriding llvm-config query resultsMichal Gorny2016-09-141-4/+9
| | | | | | | | | | | | | | | | Support overriding LLVM_* variables obtained from llvm-config when doing stand-alone builds. The override of LLVM_MAIN_SRC_DIR is necessary to provide LLVM sources when the initial directory used to build LLVM does no longer exist when compiler-rt is built stand-alone. This is especially the case when building the projects separately in temporary directories with unpredictable names. The code is based on existing CMakeLists.txt from clang. Alike clang, it extends the override to all queried variables. Differential Revision: https://reviews.llvm.org/D24005 llvm-svn: 281461

* [ELF] - Implemented --section-start, -Ttext, -Tdata, -Tbss options.George Rimar2016-09-145-0/+100
| | | | | | | | | | | | | | | | | | --section-start=sectionname=org Locate a section in the output file at the absolute address given by org. You may use this option as many times as necessary to locate multiple sections in the command line. org must be a single hexadecimal integer; for compatibility with other linkers, you may omit the leading `0x' usually associated with hexadecimal values. Note: there should be no white space between sectionname, the equals sign (“<=>”), and org. -Tbss=org -Tdata=org -Ttext=org Same as --section-start, with .bss, .data or .text as the sectionname.

* Supports adding insertion around non-insertion replacements.Eric Liu2016-09-143-23/+116
| | | | | | | | | | | | | | | | | | | | Summary: Extend `tooling::Replacements::add()` to support adding order-independent replacements. Two replacements are considered order-independent if one of the following conditions is true: - They do not overlap. (This is already supported.) - One replacement is insertion, and the other is a replacement with length > 0, and the insertion is adjecent to but not contained in the other replacement. In this case, the replacement should always change the original code instead of the inserted text.

| | | | | | | | | | | | | | Having both rename-at and rename-all both seems confusing and introduces unneeded difficulties. Allowing to use both -qualified-name and -offset at once while performing efficient renamings seems like a feature, too.
