* stop using associative comdats for SEH filter functionsBob Haarman2017-02-222-14/+3
| | | | | | | | | | | | Summary: We implement structured exception handling (SEH) by generating filter functions for functions that use exceptions. Currently, we use associative comdats to ensure that the filter functions are preserved if and only if the functions we generated them for are preserved. This can lead to problems when generating COFF objects - LLVM may decide to inline a function that uses SEH and remove its body, at which point we will end up with a comdat that COFF cannot represent. To avoid running into that situation, this change makes us not use associative comdats for SEH filter functions. We can still get the benefits we used the associative comdats for: we will always preserve filter functions we use, and dead stripping can eliminate the ones we don't use.

* [CodeGen] Note where we add ABI-specific args in ctors. NFC.George Burgess IV2017-02-224-44/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | Meta: The ultimate goal is to teach ExtParameterInfo about pass_object_size attributes. This is necessary for that, since our ExtParameterInfo is a bit buggy in C++. I plan to actually make use of this Prefix/Suffix info in the near future, but I like small single-purpose changes. Especially when those changes are hard to actually test... At the moment, some of our C++-specific CodeGen pretends that ABIs can only add arguments to the beginning of a function call. This isn't quite correct: args can be appended to the end, as well. It hasn't mattered much until now, since we seem to only use this "number of arguments added" data when calculating the ExtParameterInfo to use when making a CGFunctionInfo. Said ExtParameterInfo is currently only used for ParameterABIs (Swift) and ns_consumed (ObjC). So, this patch allows ABIs to indicate whether args they added were at the beginning or end of an argument list. We can use this information to emit ExtParameterInfos more correctly, though like said, that bit is coming soon. No tests since this is theoretically a nop. llvm-svn: 295870

* [SLP] Fix for PR32036: Vectorized horizontal reduction returning wrong resultAlexey Bataev2017-02-222-17/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: If the same value is used several times as an extra value, SLP vectorizer takes it into account only once instead of actual number of using. For example: ``` int val = 1; for (int y = 0; y < 8; y++) { for (int x = 0; x < 8; x++) { val = val + input[y * 8 + x] + 3; } } ``` We have 2 extra rguments: `1` - initial value of horizontal reduction and `3`, which is added 8*8 times to the reduction. Before the patch we added `1` to the reduction value and added once `3`, though it must be added 64 times.

* Improve support for 'decltype(auto)' in template template parameter matching.Richard Smith2017-02-222-6/+20
| | | | | | | | | | | | | | | A 'decltype(auto)' parameter can match any other kind of non-type template parameter, so should be usable in place of any other parameter in a template template argument. The standard is sadly extremely unclear on how this is supposed to work, but this seems like the obviously-correct result. It's less clear whether an 'auto' parameter should be able to match 'decltype(auto)', since the former cannot be used if the latter turns out to be used for a reference type, but if we disallow that then consistency suggests we should also disallow 'auto' matching 'T' for the same reason, defeating intended use cases of the feature. llvm-svn: 295866

* [AArch64] Extend AArch64RedundantCopyElimination to do simple copy propagation.Geoff Berry2017-02-222-43/+422
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Extend AArch64RedundantCopyElimination to catch cases where the register that is known to be zero is COPY'd in the predecessor block. Before this change, this pass would catch cases like: CBZW %W0, <BB#1> BB#1: %W0 = COPY %WZR // removed After this change, cases like the one below are also caught: %W0 = COPY %W1 CBZW %W1, <BB#1> BB#1: %W0 = COPY %WZR // removed This change results in a 4% increase in static copies removed by this pass when compiling the llvm test-suite. It also fixes regressions caused by doing post-RA copy propagation (a separate change to be put up for review shortly).

* [WebAssembly] Define a table of function signatures for runtime library calls.Dan Gohman2017-02-223-0/+1345
| | | | | | | | | | LLVM CodeGen emits references to external symbols that are never declared in LLVM IR level, so they have no declared signature. However, WebAssembly requires all functions be declared with signatures. This patch adds a table for providing signatures for known runtime libcalls that will be used in subsequent patches to emit declarations for such functions. llvm-svn: 295857

* [Support] Provide linux/magic.h fallback for older kernelsMichal Gorny2017-02-222-0/+24
| | | | | | | | | | | | | | | | | | | | | The function for distinguishing local and remote files added in r295768 unconditionally uses linux/magic.h header to provide necessary filesystem magic numbers. However, in kernel headers predating 2.6.18 the magic numbers are spread throughout multiple include files. Furthermore, LLVM did not require kernel headers being installed so far. To increase the portability across different versions of Linux kernel and different Linux systems, add CMake header checks for linux/magic.h and -- if it is missing -- the linux/nfs_fs.h and linux/smb.h headers which contained the numbers previously. Furthermore, since the numbers are static and the feature does not seem critical enough to make LLVM require kernel headers at all, add fallback constants for the case when none of the necessary headers is available.

We use the LLVM optimization remark infrastructure as it seems to be the best fit for this kind of messages. I tried to make use if the OptimizationRemarkEmitter. However, it would insert additional function passes into the pass manager to get the hotness information. The pass manager would insert them between the flatten pass and delicm, causing the ScopInfo with the flattened schedule being thrown away.

* Replace WINLOG_*** macros with LLDB_LOGPavel Labath2017-02-226-374/+244
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: The main difference here is that in the WINLOG macros you can specify log categories per call, whereas here you have to go the usual lldb route of getting a Log* variable first. While this means you have to write at least two statements, it usually means that each statement will fit on a single line, whereas fitting the WINLOG invocation on a single line was almost impossible. So the total size of code does not increase even in functions with a single log statement, and functions with more logging get shorter. The downside here is reduced flexibility in specifying the log categories, which a couple of functions used quite heavily (e.g. RefreshStateAfterStop). For these I chose a single category used most prominently and put everything into that, although a solution with multiple log variables is definitely possible.
