* [Docs] list command: lldb run <args>Jonas Devlieghere2019-05-081-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | The run command is only an abbreviation for the more verbose process launch -- <args> but it works just as with GDB and therefore should be mentioned in the GDB to LLDB command map. For educational purposes I've not listed it as the first option on the LLDB side so that new LLDB user can, if they want, also know what the "native" way is for LLDB. Here's the help documentation for the run command in lldb which gives proof: > (lldb) help run > Launch the executable in the debugger. > > Syntax: run [<run-args>] > > Command Options Usage: > run [<run-args>] > > 'run' is an abbreviation for 'process launch -c /bin/sh --' Patch by: Konrad Kleine Differential revision: https://reviews.llvm.org/D61483 llvm-svn: 360269

* [OpenMP][Clang] Support for target math functionsGheorghe-Teodor Bercea2019-05-0818-433/+693
| | | | | | | | | | | | | | | | | | | | | | | Summary: In this patch we propose a temporary solution to resolving math functions for the NVPTX toolchain, temporary until OpenMP variant is supported by Clang. We intercept the inclusion of math.h and cmath headers and if we are in the OpenMP-NVPTX case, we re-use CUDA's math function resolution mechanism.

* [compiler-rt] Make builtins test pass when using i386 gcc as host compilerNico Weber2019-05-081-1/+1
| | | | | | | | | | | | | | | | | Just-built-clang is used to compile the test, but the library is built with gcc, so the usual 80-bit FPU vs 32-bit SSE mismatch makes the floating computations not bitwise identical. Fixes PR32910, see there for details. This uses the same technique used in all the other *c3* tests, see in particular mulsc3_test.c. (It might be cleaner to add compareResultCF to fp_test.h to force the floats into 32-bit in memory, but this is the less invasive fix.)

* [Reassociation] Place moved instructions after landing padsDavid Greene2019-05-083-1/+118
| | | | | | | | | | | | | | | | | Reassociation's NegateValue moved instructions to the beginning of blocks (after PHIs) without checking for exception handling pads. It's possible for reassociation to move something into an exception handling block so we need to make sure we don't move things too early in the block. This change advances the insertion point past any exception handling pads. If the block we want to move into contains a catchswitch, we cannot move into it. In that case just create a new neg as if we had not found an existing neg to move. Differential Revision: https://reviews.llvm.org/D61089 llvm-svn: 360262

* [Support] Fix unit test for fs::is_localPetar Jovanovic2019-05-081-0/+1
| | | | | | | | | | | | | Close the temporary file after the test is done using it. If it is not closed and the file was created on NFS, it will cause the test to fail. The problem happens in the cleanup process afterwards. It first tries to delete the file but it is not really deleted. Afterwards, the program fails to delete the directory containing the file, causing the whole test to fail. Patch by Milos Stojanovic. llvm-svn: 360259
* [Sema][OpenCL] Make address space conversions a bit stricter.Anastasia Stulova2019-05-089-30/+179
| | | | | | | | | | | | | | | | | | | | | | | | The semantics for converting nested pointers between address spaces are not very well defined. Some conversions which do not really carry any meaning only produce warnings, and in some cases warnings hide invalid conversions, such as 'global int*' to 'local float*'! This patch changes the logic in checkPointerTypesForAssignment and checkAddressSpaceCast to fail properly on implicit conversions that should definitely not be permitted. We also dig deeper into the pointer types and warn on explicit conversions where the address space in a nested pointer changes, regardless of whether the address space is compatible with the corresponding pointer nesting level on the destination type.

* [DWARF] Centralize user_id <-> DWARFDIE conversionsPavel Labath2019-05-086-114/+55
| | | | | | | | | | | | | | | | | | | | | | | Summary: The logic for translating a user_id into a DWARFDIE was replicated in several places. This removes that redundancy and settles on a single implementation in SymbolFileDWARF. The reason for choosing that instead of DIERef was that we were always immediately converting the returned DIERef into a DWARFDIE anyway, which meant that one had to specify the SymbolFileDWARF argument twice (once to get the DIERef, and once to get the actual DIE). Also, passing a higher-level object (SymbolFileDWARF) into a lower-level one (DIERef) seemed like a less intuitive arrangement than doing things the other way around.

* [Support] Add error handling to sys::Process::getPageSize().Lang Hames2019-05-0812-22/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the return type of sys::Process::getPageSize to Expected<unsigned> to account for the fact that the underlying syscalls used to obtain the page size may fail (see below). For clients who use the page size as an optimization only this patch adds a new method, getPageSizeEstimate, which calls through to getPageSize but discards any error returned and substitues a "reasonable" page size estimate estimate instead. All existing LLVM clients are updated to call getPageSizeEstimate rather than getPageSize. On Unix, sys::Process::getPageSize is implemented in terms of getpagesize or sysconf, depending on which macros are set. The sysconf call is documented to return -1 on failure. On Darwin getpagesize is implemented in terms of sysconf and may also fail (though the manpage documentation does not mention this). These failures have been observed in practice when highly restrictive sandbox permissions have been applied. Without this patch, the result is that getPageSize returns -1, which wreaks havoc on any subsequent code that was assuming a sane page size value. <rdar://problem/41654857> Reviewers: dblaikie, echristo Subscribers: kristina, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D59107 llvm-svn: 360221
