* [COFF] Use COFF stubs for extern_weak functionsReid Kleckner2019-05-077-19/+87
| | | | | | | | | | | | | | | | | | | | | | | Summary: A COFF stub indirects the reference to a symbol through memory. A .refptr.$sym global variable pointer is created to refer to $sym. Typically mingw uses these for external global variable declarations, but we can use them for weak function declarations as well. Updates the dso_local classification to add a special case for extern_weak symbols on COFF in both clang and LLVM.

This patch allows the hazard recognizer to consider bundled instructions in both scheduler and hazard recognizer mode.

* [JITLink] Add support for MachO .alt_entry atoms.Lang Hames2019-05-074-12/+173
| | | | | | | | | | | | | | | | The MachO .alt_entry directive is applied to a symbol to indicate that it is locked (in terms of address layout and liveness) to its predecessor atom. I.e. it is an alternate entry point, at a fixed offset, for the previous atom. This patch updates MachOAtomGraphBuilder to check for the .alt_entry flag on symbols and add a corresponding LayoutNext edge to the atom-graph. It also updates MachOAtomGraphBuilder_x86_64 to generalize handling of the X86_64_RELOC_SUBTRACTOR relocation: previously either the minuend or subtrahend of the subtraction had to be the same as the atom being fixed up, now it is only necessary for the minuend or subtrahend to be locked (via any chain of alt_entry directives) to the atom being fixed up. llvm-svn: 360194

* Revert "[OpenMP][Clang] Support for target math functions"Jonas Devlieghere2019-05-0718-677/+431
| | | | | | | | | | | | | | This commit appears to be breaking stage-2 builds on GreenDragon. The OpenMP wrappers for cmath and math.h are copied into the root of the resource directory and cause a cyclic dependency in module 'Darwin': Darwin -> std -> Darwin. This blows up when CMake is testing for modules support and breaks all stage 2 module builds, including the ThinLTO bot and all LLDB bots.

* [InstCombine] allow sinking fneg operands through an FP min/maxSanjay Patel2019-05-072-21/+17
| | | | | | | | | Fundamentally/generally, we should not have to rely on bailouts/crippling of folds. In this particular case, I think we always recognize the inverted predicate min/max pattern, so there should not be any loss of optimization.

| | | | | | | | | | | | | | | | | | | DWARF5, 2.12 20ff says that Any debugging information entry representing a pointer or reference type [may have a DW_AT_address_class attribute]. The existing code (https://reviews.llvm.org/D29670) seems to take a quite literal interpretation of that wording. I don't see a reason why an rvalue reference isn't a reference type in the spirit of that paragraph. This patch allows rvalue references to also have address spaces. rdar://problem/50511483 Differential Revision: https://reviews.llvm.org/D61625 llvm-svn: 360176

| | | | | | | | | | | | | | | | | | When simplifying TokenFactors, we potentially iterate over all operands of a large number of TokenFactors. This causes quadratic compile times in some cases and the large token factors cause additional scalability problems elsewhere. This patch adds some limits to the number of nodes explored for the cases mentioned above.

* PostfixExpression: Use signed integers in IntegerNodePavel Labath2019-05-074-16/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is necessary to support parsing expressions like ".cfa -16 + ^", as that format is used in breakpad STACK CFI expressions. Since the PDB expressions use the same parser, this change will affect them too, but I don't believe that should be a problem in practice. If PDBs do contain the negative values, it's very likely that they are intended to be parsed the same way, and if they don't, then it doesn't matter. In case that we do ever need to handle this differently, we can always make the parser behavior customizable, or just use a different parser. To make sure that the integer size is big enough for everyone, I switch from using a (unsigned) 32-bit integer to a 64-bit (signed) one.
