Ted Kremenek 80263e5905 Allow a '0' precision in format strings (as the man page says it is okay). 
Fixes <rdar://problem/7700339>.

Johnny Chen 718ed8a6d5 Added STRHT for disassembly only and fixed a bug in AI3sthpo class where the W 
bit should be set to 0 instead of 1.

Devang Patel ed56bcfd91 Remove this test because it checks wheter optimizer handled @llvm.dbg.global_variable appropriately or not. LLVM does not use this scheme to encode debug info for global variables any more.

 2010-03-01 19:11:54 +00:00
Devang Patel d8425df136 Remove test to check bugfix in handing debug info for global variables using intrinsics. Now, debug info for global variable is encoded using metadata. The old code path is now history and there is no need to have a test to check a bug fix in old code path.

Douglas Gregor aff9c1a033 When instantiating a function-scoped enum, make sure that it and its 
enumeration constants get placed into the local instantiation hash
table. Fixes PR6375.

Torok Edwin 12b02282d9 Add command-line flag to tblgen to turn off generating comments for the new 
isel (defaults it to generate comments).
This reduces the size of the generated source file.

Chris Lattner c1a3190870 Accelerate isel dispatch for tables that start with a top-level 
OPC_SwitchOpcode to use a table lookup instead of having to go
through the interpreter for this.

Devang Patel 890644e3a7 These two tests check whether oprimizer safely ignores @llvm.dbg.stoppoint intrinsic or not. This intrinsic is not used anymore.

Devang Patel 1392621e0f This test checks whether LICM ignores @llvm.dbg.stoppoint intrinsics appropriately or not. Now, llvm does not use this intrinsic. Remove this test.

Devang Patel 4aefd92040 Remove this generic debug info intrinsic test. LLVM does not use this llvm.dbg.stoppoint intrinsic anymore. There are tests to check new implementation, which attaches location information directly with an instruction using metadata.

Douglas Gregor 604c30299d Robustify instantiation of templates when there are errors in the 
template definition. Do this both by being more tolerant of errors in
our asserts and by not dropping a variable declaration completely when
its initializer is ill-formed. Fixes the crash-on-invalid in PR6375,
but not the original issue.

John McCall 8bc2a70dfe Don't infinite-loop if TryAnnotateCXXScopeToken fails to annotate but doesn't 
signal an error.  This can happen even when the current token is '::' if
this is a ::new or ::delete expression.

This was an oversight in my recent parser refactor;  fixes PR 5825.

Douglas Gregor a04f2ca19a When looking for the instantiated declaration that corresponds to a 
given declaration in a template, make sure that the context we're

Nathan Keynes 42a5be5121 Add JIT support to the TODO list (test commit)

Chris Lattner 86878b4a1e Emit type checks late instead of early, this encourages 
structural matching code to be factored and shared this
shrinks the X86 isel table from 86537 to 83890 bytes.

llvm-svn: 97442
 2010-03-01 07:54:59 +00:00
Chris Lattner e89ca7c146 some trivial microoptimizations. 
llvm-svn: 97441
 2010-03-01 07:43:08 +00:00
Chris Lattner a44697c394 Emit a redundant check for immediates at root context, e.g. (imm 0). 
This allows formation of OpcodeSwitch for top level patterns, in
particular on X86.  This saves about 1K of data space in the x86
table and makes the dispatch much more efficient.

llvm-svn: 97440
 2010-03-01 07:27:07 +00:00
Chris Lattner 053a28a397 eliminate the CheckMultiOpcodeMatcher code and have each 
ComplexPattern at the root be generated multiple times, once
for each opcode they are part of.  This encourages factoring
because the opcode checks get treated just like everything
else in the matcher.

llvm-svn: 97439
 2010-03-01 07:17:40 +00:00
Chris Lattner f4d1775263 add a new OPC_SwitchOpcode which is semantically equivalent 
to a scope where every child starts with a CheckOpcode, but
executes more efficiently.  Enhance DAGISelMatcherOpt to 
form it.

This also fixes a bug in CheckOpcode: apparently the SDNodeInfo
objects are not pointer comparable, we have to compare the
enum name.

Zhongxing Xu 6d3cc382df Since now we store the cast type with an ElementRegion, there is 
no need to store a type with SymbolRegionValue.

Chris Lattner db5b73a77f pull MarkFlagResult out from between an EmitNode/CompleteMatch 
pair.  This encourages MorphNodeTo formation, this gets us 200
more MorphNodeTo's on X86 and shrinks the table a bit.

llvm-svn: 97434
 2010-03-01 02:33:14 +00:00
Chris Lattner 4634d9beef enhance RecordNode and RecordChild comments to indicate what 
slot they're recording into, no functionality change.

llvm-svn: 97433
 2010-03-01 02:24:17 +00:00
Chris Lattner 90b1b9d984 Emit redundant opcode checks for andimm and orimm tests at root 
so that we get grouping at the top level.

Add an optimization to reorder type check & record nodes
after opcode checks.  We prefer to expose tree shape 
matching which improves grouping and will enhance the next
optimization.
