2016-08-12CodeGen: Replace ThinLTO backend implementation with a client of LTO/Resolution.Teresa Johnson1-33/+64
Summary: This changes clang to use the llvm::lto::thinBackend function instead of its own less comprehensive ThinLTO backend implementation. Patch by Peter Collingbourne Reviewers: tejohnson, mehdi_amini Subscribers: cfe-commits, mehdi_amini Differential Revision: https://reviews.llvm.org/D21545 llvm-svn: 278541
2016-08-08[ARM] Command-line options for embedded position-independent codeOliver Stannard1-0/+6
This patch (with the corresponding ARM backend patch) adds support for some new relocation models: * Read-only position independence (ROPI): Code and read-only data is accessed PC-relative. The offsets between all code and RO data sections are known at static link time. * Read-write position independence (RWPI): Read-write data is accessed relative to a static base register. The offsets between all writeable data sections are known at static link time. These two modes are independent (they specify how different objects should be addressed), so they can be used individually or together. These modes are intended for bare-metal systems or systems with small real-time operating systems. They are designed to avoid the need for a dynamic linker, the only initialisation required is setting the static base register to an appropriate value for RWPI code. There is one C construct not currently supported by these modes: global variables initialised to the address of another global variable or function, where that address is not known at static-link time. There are a few possible ways to solve this: * Disallow this, and require the user to write their own initialisation function if they need variables like this. * Emit dynamic initialisers for these variables in the compiler, called from the .init_array section (as is currently done for C++ dynamic initialisers). We have a patch to do this, described in my original RFC email (http://lists.llvm.org/pipermail/llvm-dev/2015-December/093022.html), but the feedback from that RFC thread was that this is not something that belongs in clang. * Use a small dynamic loader to fix up these variables, by adding the difference between the load and execution address of the relevant section. This would require linker co-operation to generate a table of addresses that need fixing up. Differential Revision: https://reviews.llvm.org/D23196 llvm-svn: 278016

Patch by Jake VanAdrighem Differential Revision: http://reviews.llvm.org/D22608 llvm-svn: 276517
2016-07-22[Profile] Enable profile merging with -fprofile-generat[=<dir>]Xinliang David Li1-1/+1
This patch enables raw profile merging for this option which is the new intended behavior. llvm-svn: 276484
2016-07-15Frontend: Simplify ownership model for clang's output streams.Peter Collingbourne1-87/+60
This changes the CompilerInstance::createOutputFile function to return a std::unique_ptr<llvm::raw_ostream>, rather than an llvm::raw_ostream implicitly owned by the CompilerInstance. This in most cases required that I move ownership of the output stream to the relevant ASTConsumer. The motivation for this change is to allow BackendConsumer to be a client of interfaces such as D20268 which take ownership of the output stream. Differential Revision: http://reviews.llvm.org/D21537 llvm-svn: 275507

2016-06-23Invoke simplifycfg and sroa before instcombine.Dehao Chen1-3/+9
Summary: InstCombine needs to be performed after simplifycfg and sroa, otherwise it may make bad optimization decisions. Reviewers: davidxl, wmi, dnovillo Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D21568 llvm-svn: 273606
2016-06-22Add support for /Ob1 and -finline-hint-functions flagsHans Wennborg1-1/+2
Add support for /Ob1 (and equivalent -finline-hint-functions), which enable inlining only for functions marked inline, either explicitly (via inline keyword, for example), or implicitly (function definition in class body, for example). This works by enabling inlining pass, and adding noinline attribute to every function not marked inline. Patch by Rudy Pons <rudy.pons@ilod.org>! Differential Revision: http://reviews.llvm.org/D20647 llvm-svn: 273440
2016-06-21Invoke PruneEH pass before Sample Profile pass.Dehao Chen1-0/+1
Summary: We need to call PruneEH pass before AutoFDO pass so that some EH-related calls can get inlined in Sample Profile pass. Reviewers: davidxl, dnovillo Subscribers: junbuml, llvm-commits Differential Revision: http://reviews.llvm.org/D21197 llvm-svn: 273298

2016-05-27Add instcombine pass if sampleprofile pass is enabled.Dehao Chen1-2/+10
Summary: Sample profile pass need to have instcombine pass. A related change is http://reviews.llvm.org/D17742. But we should not explicitly add dependency between to non-analysis passes. So we add the dependency here. Reviewers: davidxl, dnovillo Subscribers: llvm-commits Differential Revision: http://reviews.llvm.org/D20502 llvm-svn: 271010

2016-05-16Change embed-bitcode linkage typeSteven Wu1-22/+51
Embedded bitcode should have private linkage instead of appending or external. Otherwise, it will cause link failure due to duplicated symbols. Also add llvm.embedded.module and llvm.cmdline to llvm.compiler.used so they don't get optimized out. rdar://problem/21555860 llvm-svn: 269679

2016-05-11Embed bitcode in object file (clang cc1 part)Steven Wu1-0/+90
Summary: Teach clang to embed bitcode inside bitcode. When -fembed-bitcode cc1 option is used, clang will embed both the input bitcode and cc1 commandline into the bitcode in special sections before compiling to the object file. Using -fembed-bitcode-marker will only introduce a marker in both sections.

2016-04-08Move EABIVersion from CodeGenOptions to TargetOptionsSaleem Abdulrasool1-1/+1
It is possible to argue that the EABIVersion field is similar in spirit to the ABI field in TargetOptions. It represents the embedded ABI that the target follows. This will allow us to thread this information into the target information construction. llvm-svn: 265807
2016-04-08revert SVN r265702, r265640Saleem Abdulrasool1-2/+2
Revert the two changes to thread CodeGenOptions into the TargetInfo allocation and to fix the layering violation by moving CodeGenOptions into Basic. Code Generation is arguably not particularly "basic". This addresses Richard's post-commit review comments. This change purely does the mechanical revert and will be followed up with an alternate approach to thread the desired information into TargetInfo. llvm-svn: 265806
2016-04-07Basic: move CodeGenOptions from FrontendSaleem Abdulrasool1-2/+2
This is a mechanical move of CodeGenOptions from libFrontend to libBasic. This fixes the layering violation introduced earlier by threading CodeGenOptions into TargetInfo. It should also fix the modules based self-hosting builds. NFC. llvm-svn: 265702
2016-03-15[ThinLTO] Clang side of renaming of function index (NFC)Teresa Johnson1-18/+18

2016-03-04Make TargetInfo store an actual DataLayout instead of a string.James Y Knight1-6/+6
Use it to calculate UserLabelPrefix, instead of specifying it (often incorrectly). Note that the *actual* user label prefix has always come from the DataLayout, and is handled within LLVM. The main thing clang's TargetInfo::UserLabelPrefix did was to set the #define value. Having these be different from each-other is just silly. Differential Revision: http://reviews.llvm.org/D17183 llvm-svn: 262737
2016-03-02[PGO] Change profile use cc1 option to handle IR level profilesRong Xu1-0/+2
This patch changes cc1 option for PGO profile use from -fprofile-instr-use=<path> to -fprofile-instrument-use-path=<path>. -fprofile-instr-use=<path> is now a driver only option. In addition to decouple the cc1 option from the driver level option, this patch also enables IR level profile use. cc1 option handling now reads the profile header and sets CodeGenOpt ProfileUse (valid values are {None, Clang, LLVM} -- this is a common enum for -fprofile-instrument={}, for the profile instrumentation), and invoke the pipeline to enable the respective PGO use pass. Reviewers: silvas, davidxl Differential Revision: http://reviews.llvm.org/D17737 llvm-svn: 262515
2016-02-29[PGO] clang cc1 option change to enable IR level instrumentationRong Xu1-0/+6
This patch expands cc1 option -fprofile-instrument= with a new value: -fprofile-instrument=llvm which enables IR level PGO instrumentation. Reviewers: davidxl, silvas Differential Revision: http://reviews.llvm.org/D17622 llvm-svn: 262239

2016-02-04[PGO] cc1 option name change for profile instrumentationRong Xu1-1/+1
This patch changes cc1 option -fprofile-instr-generate to an enum option -fprofile-instrument={clang|none}. It also changes cc1 options -fprofile-instr-generate= to -fprofile-instrument-path=. The driver level option -fprofile-instr-generate and -fprofile-instr-generate= remain intact. This change will pave the way to integrate new PGO instrumentation in IR level.

2016-01-08[ThinLTO] Leverage new in-place renaming supportTeresa Johnson1-16/+33
Due to the new in-place renaming support added in r257174, we no longer need to invoke ThinLTO global renaming from clang. It will be invoked on the module in the FunctionImport pass (by an immediately following llvm commit). As a result, we don't need to load the FunctionInfoIndex as early, so that is moved down into EmitAssemblyHelper::EmitAssembly. llvm-svn: 257179

2015-12-21[clang-cl] Add support for /BreproDavid Majnemer1-0/+2
The /Brepro flag controls whether or not the compiler should embed timestamps into the object file. Object files which do not embed timestamps are not suitable for incremental linking but are suitable for hermetic build systems and staged self-hosts of clang. A normal clang spelling of this flag has been added, -mincremental-linker-compatible. llvm-svn: 256204
