* Move AliasedSymbol to MachObjectWriter.Rafael Espindola2015-04-175-21/+18

* [mips] Teach the delay slot filler to remove needless KILL instructions.Vasileios Kalintiris2015-04-172-11/+44
| | | | | | | | | | | | | | | | | | Summary: Previously, the presence of KILL instructions would block valid candidates from filling a specific delay slot. With the elimination of the KILL instructions, in the appropriate range, we are able to fill more slots and keep the information from future def/use analysis consistent.

* [mips] Move ABI-dependent register selections to MipsABIInfo. NFC.Daniel Sanders2015-04-176-49/+84
| | | | | | | | | | | | | | | | | | | | | Summary: For example, a common idiom was 'isN64 ? Mips::SP_64 : Mips::SP'. This has been moved to MipsABIInfo and replaced with 'ABI.GetStackPtr()'. There are others that should also be moved. This patch sticks to the ones that are obviously non-functional. The others have minor mistakes that need fixing at the same time, mostly involving checks for 64-bit GPR's instead of checks for 64-bit pointers.

* Write relocation sections contiguously.Rafael Espindola2015-04-175-11/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linkers normally read all the relocations upfront to compute the references between sections. Putting them together is a bit more cache friendly. I benchmarked linking a Release+Asserts clang with gold on a vm. I tried all 4 combinations of --gc-sections/no --gc-section hot and cold cache. I cleared the cache with echo 3 > /proc/sys/vm/drop_caches and warmed it up by running the link once before timing the subsequent ones. With cold cache and --gc-sections the time goes from 1.86130781665 +- 0.01713126697463843 seconds to 1.82370735105 +- 0.014127522318814516 seconds With cold cache and no --gc-sections the time goes from 1.6087245435500002 +- 0.012999066825178644 seconds to 1.5687122041500001 +- 0.013145850126026619 seconds With hot cache and no --gc-sections the time goes from 0.926200939 ( +- 0.33% ) seconds to 0.907200079 ( +- 0.31% ) seconds With hot cache and gc sections the time goes from 1.183038049 ( +- 0.34% ) seconds to 1.147355862 ( +- 0.39% ) seconds llvm-svn: 235165

* [SEH] Reimplement x64 SEH using WinEHPrepareReid Kleckner2015-04-1719-356/+420
| | | | | | | | | | | | | | | | This now emits simple, unoptimized xdata tables for __C_specific_handler based on the handlers listed in @llvm.eh.actions calls produced by WinEHPrepare. This adds support for running __finally blocks when exceptions are thrown, and removes the old landingpad fan-in codepath. I ran some manual execution tests on small basic test cases with and without optimization, as well as on Chrome base_unittests, which uses a small amount of SEH. I'm sure there are bugs, and we may need to revert. llvm-svn: 235154

| | | | | | | | | | | | | | | | | | | | | | | Summary: An alternative is to use a worklist approach. However, that approach would break the traversing order so that we couldn't lookup SeenExprs efficiently. I don't see a clear winner here, so I picked the easier approach.

* [opaque pointer type] Add textual IR support for explicit type parameter to ↵David Blaikie2015-04-16560-1503/+1498
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | the call instruction See r230786 and r230794 for similar changes to gep and load respectively. Call is a bit different because it often doesn't have a single explicit type - usually the type is deduced from the arguments, and just the return type is explicit. In those cases there's no need to change the IR. When that's not the case, the IR usually contains the pointer type of the first operand - but since typed pointers are going away, that representation is insufficient so I'm just stripping the "pointerness" of the explicit type away. This does make the IR a bit weird - it /sort of/ reads like the type of the first operand: "call void () %x(" but %x is actually of type "void ()*" and will eventually be just of type "ptr". But this seems not too bad and I don't think it would benefit from repeating the type ("void (), void () * %x(" and then eventually "void (), ptr %x(") as has been done with gep and load. This also has a side benefit: since the explicit type is no longer a pointer, there's no ambiguity between an explicit type and a function that returns a function pointer. Previously this case needed an explicit type (eg: a function returning a void() function was written as "call void () () * @x(" rather than "call void () * @x(" because of the ambiguity between a function returning a pointer to a void() function and a function returning void). No ambiguity means even function pointer return types can just be written alone, without writing the whole function's type. This leaves /only/ the varargs case where the explicit type is required. Given the special type syntax in call instructions, the regex-fu used for migration was a bit more involved in its own unique way (as every one of these is) so here it is. Use it in conjunction with the apply.sh script and associated find/xargs commands I've provided in rr230786 to migrate your out of tree tests. Do let me know if any of this doesn't cover your cases & we can iterate on a more general script/regexes to help others with out of tree tests. About 9 test cases couldn't be automatically migrated - half of those were functions returning function pointers, where I just had to manually delete the function argument types now that we didn't need an explicit function type there. The other half were typedefs of function types used in calls - just had to manually drop the * from those. import fileinput import sys import re pat = re.compile(r'((?:=|:|^|\s)call\s(?:[^@]*?))(\s*$|\s*(?:(?:\[\[[a-zA-Z0-9_]+\]\]|[@%](?:(")?[\\\?@a-zA-Z0-9_.]*?(?(3)"|)|{{.*}}))(?:\(|$)|undef|inttoptr|bitcast|null|asm).*$)') addrspace_end = re.compile(r"addrspace\(\d+\)\s*\*$") func_end = re.compile("(?:void.*|\)\s*)\*$") def conv(match, line): if not match or re.search(addrspace_end, match.group(1)) or not re.search(func_end, match.group(1)): return line return line[:match.start()] + match.group(1)[:match.group(1).rfind('*')].rstrip() + match.group(2) + line[match.end():] for line in sys.stdin: sys.stdout.write(conv(re.search(pat, line), line)) llvm-svn: 235145

* [IR] Introduce a dereferenceable_or_null(N) attribute.Sanjoy Das2015-04-1617-31/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Summary: If a pointer is marked as dereferenceable_or_null(N), LLVM assumes it is either `null` or `dereferenceable(N)` or both. This change only introduces the attribute and adds a token test case for the `llvm-as` / `llvm-dis`. It does not hook up other parts of the optimizer to actually exploit the attribute -- those changes will come later. For pointers in address space 0, `dereferenceable(N)` is now exactly equivalent to `dereferenceable_or_null(N)` && `nonnull`. For other address spaces, `dereferenceable(N)` is potentially weaker than `dereferenceable_or_null(N)` && `nonnull` (since we could have a null `dereferenceable(N)` pointer). The motivating case for this change is Java (and other managed languages), where pointers are either `null` or dereferenceable up to some usually known-at-compile-time constant offset.

| | | | | | | | | | | | | | | | This is very similar to D8486 / r232852 (vperm2). If we treat insertps intrinsics as shufflevectors, we can optimize them better. I've left all but the full zero case of the zero mask variants out of this patch. I don't think those can be converted into a single shuffle in all cases, but I'd be happy to be proven wrong as I was for vperm2f128. Either way, we'd need to support whatever sequence we come up with for those cases in the backend before converting them here. Differential Revision: http://reviews.llvm.org/D8833 llvm-svn: 235124
