2013-04-11Add a function to check if an argument list is too long.Rafael Espindola
This will be used in clang to decide if it should create an @file or not. It will be tested on the clang side. Patch by Nathan Froyd. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179285 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-11Fix MachO's getRelocationAdditionalInfo.Rafael Espindola
It was returning the loaded address of the section containing the relocation, which really doesn't seem to be the intent of this function. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179255 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-10MC: Support COFF image-relative MCSymbolRefsNico Rieck
Add support for the COFF relocation types IMAGE_REL_I386_DIR32NB and IMAGE_REL_AMD64_ADDR32NB for 32- and 64-bit respectively. These are similar to normal 4-byte relocations except that they do not include the base address of the image. Image-relative relocations are used for debug information (32-bit) and SEH unwind tables (64-bit). A new MCSymbolRef variant called 'VK_COFF_IMGREL32' is introduced to specify such relocations. For AT&T assembly, this variant can be accessed using the symbol suffix '@imgrel'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179240 91177308-0d34-0410-b5e6-96231b3b80d8
2013-04-10Revert "Update the version of dwarf we say we're emitting to at least 3."Eric Christopher

2013-04-10Reapply r179115, but use parsePrimaryExpression a little more judiciously.Chad Rosier
Test cases that regressed due to r179115, plus a few more, were added in r179182. Original commit message below: [ms-inline asm] Use parsePrimaryExpr in lieu of parseExpression if we need to parse an identifier. Otherwise, parseExpression may parse multiple tokens, which makes it impossible to properly compute an immediate displacement. An example of such a case is the source operand (i.e., [Symbol + ImmDisp]) in the below example: __asm mov eax, [Symbol + ImmDisp] Part of rdar://13611297 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179187 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-10Generalize the PassConfig API and remove addFinalizeRegAlloc().Andrew Trick
The target hooks are getting out of hand. What does it mean to run before or after regalloc anyway? Allowing either Pass* or AnalysisID pass identification should make it much easier for targets to use the substitutePass and insertPass APIs, and create less need for badly named target hooks. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179140 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09Add support for bottom-up SLP vectorization infrastructure.Nadav Rotem
This commit adds the infrastructure for performing bottom-up SLP vectorization (and other optimizations) on parallel computations. The infrastructure has three potential users: 1. The loop vectorizer needs to be able to vectorize AOS data structures such as (sum += A[i] + A[i+1]). 2. The BB-vectorizer needs this infrastructure for bottom-up SLP vectorization, because bottom-up vectorization is faster to compute. 3. A loop-roller needs to be able to analyze consecutive chains and roll them into a loop, in order to reduce code size. A loop roller does not need to create vector instructions, and this infrastructure separates the chain analysis from the vectorization. This patch also includes a simple (100 LOC) bottom up SLP vectorizer that uses the infrastructure, and can vectorize this code: void SAXPY(int *x, int *y, int a, int i) { x[i] = a * x[i] + y[i]; x[i+1] = a * x[i+1] + y[i+1]; x[i+2] = a * x[i+2] + y[i+2]; x[i+3] = a * x[i+3] + y[i+3]; } git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179117 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09[ms-inline asm] Maintain a StringRef to reference a symbol in a parsed operand,Chad Rosier
rather than deriving the StringRef from the Start and End SMLocs. Using the Start and End SMLocs works fine for operands such as [Symbol], but not for operands such as [Symbol + ImmDisp]. All existing test cases that reference a variable exercise this patch. rdar://13602265 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179109 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-09Fix PointerIntPair to be enum class compatible.Joe Groff
Some parts of PointerIntPair assumed that the IntType of the pair was implicitly convertible to intptr_t, which is not the case for enum class values. Add a static_cast<intptr_t> to make these conversions explicit and allow PointerIntPair to be used with an enum class IntType. While we're here, rename some of the argument values so we don't have variables named "Int" floating around. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@179073 91177308-0d34-0410-b5e6-96231b3b80d8

2013-04-07TargetLowering: Fix getTypeConversion handling of extended vector typesArnold Schwaighofer
The code in getTypeConversion attempts to promote the element vector type before it trys to split or widen the vector. After it failed finding a legal vector type by promoting it would continue using the promoted vector element type. Thereby missing legal splitted vector types. For example the type v32i32 that has a legal split of 4 x v3i32 on x86/sse2 would be transformed to: v32i256 and from there on successively split to: v16i256, v8i256, v1i256 and then finally ends up as an i64 type. By resetting the vector element type to the original vector element type that existed before the promotion the code will attempt to split the vector type to smaller vector widths of the same type. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@178999 91177308-0d34-0410-b5e6-96231b3b80d8
