* [CodeGen] Clarify comment about COFF common symbol alignmentShoaib Meenai2019-01-091-2/+6
| | | | | | | | | | | | | After a discussion on the commit thread, it seems the 32 byte alignment limitation is an MSVC toolchain artifact, not an inherent COFF restriction. Clarify the comment accordingly, since saying COFF in the comment but using isKnownWindowsMSVCEnvironment in the conditional is confusing. Also add a newline before the comment, which is consistent with the local style. Differential Revision: https://reviews.llvm.org/D56466 llvm-svn: 350754
* [CodeGen] Ignore return sext/zext attributes of unused results for tail callsFrancis Visoiu Mistrih2019-01-092-0/+51
| | | | | | | | | | | | | If the caller's return type does not have a zeroext attribute but the callee does a tail call zeroext, we won't consider the tail call during CodeGenPrepare because the attributes don't match. However, if the result of the tail call has no uses, it makes sense to drop the sext/zext attributes. Differential Revision: https://reviews.llvm.org/D56486 llvm-svn: 350753

* ELF: create "container" sections from PT_LOAD segmentsPavel Labath2019-01-0910-58/+488
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: This is the result of the discussion in D55356, where it was suggested as a solution to representing the addresses that logically belong to a module in memory, but are not a part of any of its sections. The ELF PT_LOAD segments are similar to the MachO "load commands", except that the relationship between them and the object file sections is a bit weaker. While in the MachO case, the sections belonging to a specific segment are placed directly inside it in the object file logical structur, in the ELF case, the sections and segments form two separate hierarchies. This means that it is in theory possible to create an elf file where only a part of a section would belong to some segment (and another part to a different one). However, I am not aware of any tool which would produce such a file (and most tools will have problems ingesting them), so this means it is still possible to follow the MachO model and make sections children of the PT_LOAD segments. In case we run into (corrupt?) files with overlapping sections, I have added code (and tests) which adjusts the sizes and/or drops the offending sections in order to present a reasonable image to the upper layers of LLDB. This is mostly done for completeness, as I don't anticipate running into this situation in the real world. However, if we do run into it, and the current behavior is not suitable for some reason, we can implement this logic differently.

* [AST] Move back BasePathSize to the bit-fields of CastExprBruno Ricci2019-01-096-125/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | The number of trailing CXXBaseSpecifiers in CastExpr was moved from CastExprBitfields to a trailing object in r338489 (D50050). At this time these bit-fields classes were only 32 bits wide. However later r345459 widened these bit-field classes to 64 bits. The reason for this change was that on 64 bit archs alignment requirements caused 4 bytes of padding after the Stmt sub-object in nearly all expression classes. Reusing this padding yielded an >10% reduction in the size used by all statement/expressions when parsing all of Boost (on a 64 bit arch). This increased the size of statement/expressions for 32 bits archs, but this can be mitigated by moving more data to the bit-fields of Stmt (and moreover most people now care about 64 bits archs as a host). Therefore move back the number of CXXBaseSpecifiers in CastExpr to the bit-fields of Stmt. This in effect mostly revert r338489 while keeping the added test.

| | | | | | | | | | | | | | | | On AIX, attempting (without root) to set the sticky bit on a file with the `chmod` utility will give: ``` chmod: not all requested changes were made to <file> ``` The same occurs when modifying other permission bits on a file with the sticky bit already set. It seems that the `chmod` function will report success despite failing to set the sticky bit. llvm-svn: 350735
* Incorrect implicit data-sharing for nested tasksAlexey Bataev2019-01-092-9/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: There is a minor issue in how the implicit data-sharings for nested tasks are computed. For the following example: ``` int x; #pragma omp task shared(x) #pragma omp task x++; ``` We compute an implicit data-sharing of shared for `x` in the second task although I think that it should be firstprivate. Below you can find the part of the OpenMP spec that covers this example: - // In a task generating construct, if no default clause is present, a variable for which the data-sharing attribute is not determined by the rules above and that in the enclosing context is determined to be shared by all implicit tasks bound to the current team is shared.// - //In a task generating construct, if no default clause is present, a variable for which the data-sharing attribute is not determined by the rules above is firstprivate.// Since each implicit-task has its own copy of `x`, we shouldn't apply the first rule.

| | | | | | | | | | | | | | | | | | | | When GNU objdump dumps the input with -d it prints the symbol addresses, for example: 0000000000000031 <foo>: 31: 00 00 add %al,(%rax) ... llvm-objdump currently does not do that. Patch changes the behavior to match the GNU objdump. That is useful for implementing -z/--disassemble-zeroes (D56083), it allows omitting first zero bytes and keep the information about the symbol address in the output.
