* clang-format: distinguish ObjC call subexpressions after r355434Krasimir Georgiev2019-03-112-2/+47
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: The revision r355434 had the unfortunate side-effect that it started to recognize certain ObjC expressions with a call subexpression followed by a `a->b` subexpression as C++ lambda expressions. This patch adds a bit of logic to handle these cases and documents them in tests. The commented-out test cases in the new test suite are ones that were problematic before r355434.

* Add "operator bool" to SB APIsPavel Labath2019-03-11168-18/+551
| | | | | | | | | | | | | | | | | | | | | | | Summary: Our python version of the SB API has (the python equivalent of) operator bool, but the C++ version doesn't. This is because our python operators are added by modify-python-lldb.py, which performs postprocessing on the swig-generated interface files. In this patch, I add the "operator bool" to all SB classes which have an IsValid method (which is the same logic used by modify-python-lldb.py). This way, we make the two interfaces more constent, and it allows us to rely on swig's automatic syntesis of python __nonzero__ methods instead of doing manual fixups.

* [CGP] Limit distance between overflow math and cmpSam Parker2019-03-112-0/+67
| | | | | | | | | | | | | | | Inserting an overflowing arithmetic intrinsic can increase register pressure by producing two values at a point where only one is needed, while the second use maybe several blocks away. This increase in pressure is likely to be more detrimental on performance than rematerialising one of the original instructions. So, check that the arithmetic and compare instructions are no further apart than their immediate successor/predecessor. Differential Revision: https://reviews.llvm.org/D59024 llvm-svn: 355823
* [JumpThreading] Retain debug info when replacing branch instructionsJeremy Morse2019-03-112-2/+46
| | | | | | | | | | | | | | | | | | | | Fixes bug 37966: https://bugs.llvm.org/show_bug.cgi?id=37966 The Jump Threading pass will replace certain conditional branch instructions with unconditional branches when it can prove that only one branch can occur. Prior to this patch, it would not carry the debug info from the old instruction to the new one. This patch fixes the bug described by copying the debug info from the conditional branch instruction to the new unconditional branch instruction, and adds a regression test for the Jump Threading pass that covers this case.

* [llvm-objcopy] - Fix --compress-debug-sections when there are relocations.George Rimar2019-03-116-19/+47
| | | | | | | | | | | | | | | When --compress-debug-sections is given, llvm-objcopy removes the uncompressed sections and adds compressed to the section list. This makes all the pointers to old sections to be outdated. Currently, code already has logic for replacing the target sections of the relocation sections. But we also have to update the relocations by themselves. This fixes https://bugs.llvm.org/show_bug.cgi?id=40885. Differential revision: https://reviews.llvm.org/D58960 llvm-svn: 355821

* [Support/Endian] Add support for endian-specific enumsPavel Labath2019-03-113-0/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Binary formats often include various enumerations or bitsets, but using endian-specific types for accessing them is tricky because they currently only support integral types. This is particularly true for scoped enums (enum class), as these are not implicitly convertible to integral types, and so one has to perform two casts just to read the enum value. This fixes that support by adding first-class support for enumeration types to endian-specific types. The support for them was already almost working -- all I needed to do was overload getSwappedBytes for enumeration types (which casts the enum to its underlying type and performs the conversion there). I also add some convenience template aliases to simplify declaring endian-specific enums.

* Quiet command regex instructions during batch executionDave Lee2019-03-1013-24/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Within .lldbinit, regex commands can be structured as a list of substitutions over multiple lines. It's possible that this is uninentional, but it works and has benefits. For example: command regex <command-name> s/pat1/repl1/ s/pat2/repl2/ ... I use this form of `command regex` in my `~/.lldbinit`, because it makes it clearer to write and read compared to a single line definition, because multiline substitutions don't need to be quoted, and are broken up one per line. However, multiline definitions result in usage instructions being printed for each use. The result is that every time I run `lldb`, I get a dozen or more lines of noise. With this change, the instructions are only printed when `command regex` is invoked interactively, or from a terminal, neither of which are true when lldb is sourcing `~/.lldbinit`.

Clang verifies this in the frontend when it creates the intrinsics from builtins, but the backend would still lower invalid immediates.

| | | | | | | | | | | | | | | | | | for immAllZerosV/immAllOnesV. Remove bitcasts from X86 patterns that are no longer necessary." Includes a fix to emit a CheckOpcode for build_vector when immAllZerosV/immAllOnesV is used as a pattern root. This means it can't be used to look through bitcasts when used as a root, but that's probably ok. This extra CheckOpcode will ensure that the first match in the isel table will be a SwitchOpcode which is needed by the caching optimization in the ISel Matcher. Original commit message: Previously we had build_vector PatFrags that called ISD::isBuildVectorAllZeros/Ones. Internally the ISD::isBuildVectorAllZeros/Ones look through bitcasts, but we aren't able to take advantage of that in isel. Instead of we have to canonicalize the types of the all zeros/ones build_vectors and insert bitcasts. Then we have to pattern match those exact bitcasts. By emitting specific matchers for these 2 nodes, we can make isel look through any bitcasts without needing to explicitly match them. We should also be able to remove the canonicalization to vXi32 from lowering, but I've left that for a follow up. This removes something like 40,000 bytes from the X86 isel table.

| | | | | | | | | | | | | | | | | | The --force-interactive option was introduced in SVN 1.8, and trying to pass it to older SVN clients causes an error; CentOS 7 includes SVN 1.7, for example, so this makes `git llvm` not usable out of the box. Older clients would be interactive by default anyway [1], so just don't pass the option if it's not supported. An alternative would be to check the version instead of checking the help text, but I think directly detecting the presence of the option is more direct.
