2011-10-20Refactor code from inlining and globalopt that checks whether a function ↵Eli Friedman
definition is unused, and enhance it so it can tell that functions which are only used by a blockaddress are in fact dead. This probably doesn't happen much on most code, but the Linux kernel's _THIS_IP_ can trigger this issue with blockaddress. (GlobalDCE can also handle the given tescase, but we only run that at -O3.) Found while looking at PR11180. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142572 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-19Improve code generation for vselect on SSE2:Nadav Rotem
When checking the availability of instructions using the TLI, a 'promoted' instruction IS available. It means that the value is bitcasted to another type for which there is an operation. The correct check for the availablity of an instruction is to check if it should be expanded. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142542 91177308-0d34-0410-b5e6-96231b3b80d8

2011-10-19Use literal pool loads instead of MOVW/MOVT for materializing global ↵James Molloy
addresses when optimizing for size. On spec/gcc, this caused a codesize improvement of ~1.9% for ARM mode and ~4.9% for Thumb(2) mode. This is codesize including literal pools. The pools themselves doubled in size for ARM mode and quintupled for Thumb mode, leaving suggestion that there is still perhaps redundancy in LLVM's use of constant pools that could be decreased by sharing entries. Fixes PR11087. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142530 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Document PasteDavid Greene
Document paste as a shorthand for !strconcat. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142528 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Document NAMEDavid Greene
Document NAME as a special member of def records that should not be defined anywhere else. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142527 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Add Paste TestDavid Greene
This tests TableGen's paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142526 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Implement PasteDavid Greene
Add a paste operator '#' to take two identifier-like strings and joint them. Internally paste gets represented as a !strconcat() with any necessary casts to string added. This will be used to implement basic for loop functionality as in: for i = [0, 1, 2, 3, 4, 5, 6, 7] { def R#i : Register<...> } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142525 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Process NAMEDavid Greene
During multiclass def instantiation, replace NAME in any expressions with the value of the def or defm ID. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142524 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Process Defm Prefix as InitDavid Greene
Parse and process a defm prefix as an Init expression. This allows paste operations to create defm prefixes. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142523 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Parse Def ID as ValueDavid Greene
Allow def and defm IDs to be general values. We need this for paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142522 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Don't Parse Object Body as a NameDavid Greene
Stop parsing a value if we are in name parsing mode and we see a left brace. A left brace indicates the start of an object body when we are parsing a name. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142521 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Use Parse ModeDavid Greene
Augment the value parser to respect the parse mode and not error if an ID doesn't map to an object and we are in name parsing mode. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142520 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Make ID Parsing More FlexibleDavid Greene
Add a mode control to value and ID parsers. The two modes are: - Parse a value. Expect the parsed ID to map to an existing object. - Parse a name. Expect the parsed ID to not map to any existing object. The first is used when parsing an identifier to be looked up, for example a record field or template argument. The second is used for parsing declarations. Paste functionality implies that declarations can contain arbitrary expressions so we need to be able to call into the general value parser to parse declarations with paste operators. So we need a way to parse a value-like thing without expecting that the result will map to some existing object. This parse mode provides that. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142519 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Add NAME MemberDavid Greene
Add a Value named "NAME" to each Record. This will be set to the def or defm name when instantiating multiclasses. This will replace the #NAME# processing hack once paste functionality is in place. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142518 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Fix Name AccessDavid Greene
Get the Record name as a string explicitly to avoid asserts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142517 91177308-0d34-0410-b5e6-96231b3b80d8

Get the Record name as a string explicitly to avoid asserts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142515 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Fix Name AccessDavid Greene
Get the Record name by string explicitly to avoid potential asserts. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142514 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Disambiguate Numbers and IdentifiersDavid Greene
Use lookahead to determine whether a number is really a number or is part of something forming an identifier. This won't come into play until the paste operator is recognized as a unique token. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142513 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Add PeekDavid Greene
Add a peek function to let the Lexer look at a character arbitrarily far ahead in the stream without consuming anything. We need this to disambiguate numbers and operands of a paste operation. For example: def foo#8i Without lookahead the lexer will treat '8' as a number rather than as part of a string to be pasted to form an identifier. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142512 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Resolve Record NamesDavid Greene
When resolving Record values, be sure to update the Record name as it may contain references to the value. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142511 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Allow Names Changes on Unregistered RecordsDavid Greene
Add Record names to be changed even on Records that aren't yet registered. We need to be able to do this for paste functionality because we do not want to register def names before they are unique and that can only happen once all paste operations are done. This change lets us update Record names formed by paste operations and register the result later. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142510 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Call Record InitializerDavid Greene
Call the common Record initializer code from constructors. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142509 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Add Name Init Record ConstructorDavid Greene
Add a Record constructor that takes the Record name as an Init. This is more work toward paste functionality. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142508 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Fix 80-col ViolationDavid Greene
Split up the initializer list for Record to avoid 80-col issues. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142507 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Fix Name AccessDavid Greene

2011-10-19Fix Name CheckDavid Greene
Avoid a potential assert by asking for record names as strings explicitly. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142503 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-19Fix Name CheckDavid Greene
Record names may not be fully resolved at this point so ask for the record name as a string explicitly. This avoids a potential assert. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@142502 91177308-0d34-0410-b5e6-96231b3b80d8
