* Implement trampoline step-through for Windows-x86.Stephane Sezer2017-09-221-1/+43
| | | | | | | | | | | | | | | | | | Summary: This is required to be able to step through calls to external functions that are not properly marked with __declspec(dllimport). When a call like this is emitted, the linker will inject a trampoline to produce an indirect call through the IAT.

* Initial patchset to get the testsuite running against armv7 and arm64 iOS ↵Jason Molenda2017-09-2288-163/+486
| | | | | | | | | | | | | | | | | | | | | | | devices. Normal customer devices won't be able to run these devices, we're hoping to get a public facing bot set up at some point. Both devices pass the testsuite without any errors or failures. I have seen some instability with the armv7 test runs, I may submit additional patches to address this. arm64 looks good. I'll be watching the bots for the rest of today; if any problems are introduced by this patch I'll revert it - if anyone sees a problem with their bot that I don't see, please do the same. I know it's a rather large patch. One change I had to make specifically for iOS devices was that debugserver can't create files. There were several tests that launch the inferior process redirecting its output to a file, then they retrieve the file. They were not trying to test file redirection in these tests, so I rewrote those to write their output to a file directly. llvm-svn: 314038
* DR1113: anonymous namespaces formally give their contents internal linkage.Richard Smith2017-09-227-10/+69
| | | | | | | | | | | | | | | | | | | | This doesn't affect our code generation in any material way -- we already give such declarations internal linkage from a codegen perspective -- but it has some subtle effects on code validity. We suppress the 'L' (internal linkage) marker for mangled names in anonymous namespaces, because it is redundant (the information is already carried by the namespace); this deviates from GCC's behavior if a variable or function in an anonymous namespace is redundantly declared 'static' (where GCC does include the 'L'), but GCC's behavior is incoherent because such a declaration can be validly declared with or without the 'static'. We still deviate from the standard in one regard here: extern "C" declarations in anonymous namespaces are still granted external linkage. Changing those does not appear to have been an intentional consequence of the standard change in DR1113. llvm-svn: 314037

* [CodeGen][ObjC] Build the global block structure before emitting theAkira Hatanaka2017-09-225-17/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | body of global block invoke functions. This commit fixes an infinite loop in IRGen that occurs when compiling the following code: void FUNC2() { static void (^const block1)(int) = ^(int a){ if (a--) block1(a); }; } This is how IRGen gets stuck in the infinite loop: 1. GenerateBlockFunction is called to emit the body of "block1". 2. GetAddrOfGlobalBlock is called to get the address of "block1". The function calls getAddrOfGlobalBlockIfEmitted to check whether the global block has been emitted. If it hasn't been emitted, it then tries to emit the body of the block function by calling GenerateBlockFunction, which goes back to step 1. This commit prevents the inifinite loop by building the global block in GenerateBlockFunction before emitting the body of the block function. rdar://problem/34541684 Differential Revision: https://reviews.llvm.org/D38118 llvm-svn: 314029

* [x86] swap order of srl (and X, C1), C2 when it saves sizeSanjay Patel2017-09-229-288/+331
| | | | | | | | | | | | | | The (non-)obvious win comes from saving 3 bytes by using the 0x83 'and' opcode variant instead of 0x81. There are also better improvements based on known-bits that allow us to eliminate the mask entirely. As noted, this could be extended. There are potentially other wins from always shifting first, but doing that reveals a tangle of problems in other pattern matching. We do this transform generically in instcombine, but we often have icmp IR that doesn't match that pattern, so we must account for this in the backend.

| | | | | | | | | | | | | | | | | | For the triple thumbv7-apple-ios8.0.0 ssize_t is long and size_t is unsigned long, while NSInteger is int and NSUinteger is unsigned int. Following https://developer.apple.com/library/content/documentation/Cocoa/Conceptual/Strings/Articles/formatSpecifiers.html Clang catches it and insert a cast to long, for example printf("%zd", getNSInteger()) will be replaced with printf("%zd", (long)getNSInteger()) but since the underlying type of ssize_t is long the specifier "%zd" is not getting replaced.

* [Coverage] Add an option to emit limited coverage infoVedant Kumar2017-09-222-0/+13
| | | | | | | | | | | | | | | | | | | | | Add an option to emit limited coverage info for unused decls. It's just a cl::opt for now to allow us to experiment quickly. When building llc, this results in an 84% size reduction in the llvm_covmap section, and a similar size reduction in the llvm_prf_names section. In practice I expect the size reduction to be roughly quadratic with the size of the program. The downside is that coverage for headers will no longer be complete. This will make the line/function/region coverage metrics incorrect, since they will be artificially high. One mitigation would be to somehow disable those metrics when using limited-coverage=true.
