* GlobalValue: Automatically reset visibility when setting local linkageDuncan P. N. Exon Smith2014-05-20
| | | | | | | | | | | | | | | r208264 started asserting in `setLinkage()` and `setVisibility()` that visibility and linkage are compatible. There are a few places in clang where visibility is set first, and then linkage later, so the assert fires. In `setLinkage()`, it's clear what the visibility *should* be, so rather than updating all the call sites just automatically fix the visibility. The testcase for this is for *clang*, so it'll follow separately in cfe. PR19760 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209227 91177308-0d34-0410-b5e6-96231b3b80d8

* TableGen: convert InstAlias's Emit bit to an int.Tim Northover2014-05-20
| | | | | | | | | | | | | When multiple aliases overlap, the correct string to print can often be determined purely by considering the InstAlias declarations in some particular order. This allows the user to specify that order manually when desired, without resorting to hacking around with the default lexicographical order on Record instantiation, which is error-prone and ugly. I was also mistaken about "add w2, w3, w4" being the same as "add w2, w3, w4, uxtw". That's only true if Rn is the stack pointer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209199 91177308-0d34-0410-b5e6-96231b3b80d8

* Flip on vectorization of bswap intrinsics.Benjamin Kramer2014-05-19

* Target: remove old constructors for CallLoweringInfoSaleem Abdulrasool2014-05-17
| | | | | | | | | | This is mostly a mechanical change changing all the call sites to the newer chained-function construction pattern. This removes the horrible 15-parameter constructor for the CallLoweringInfo in favour of setting properties of the call via chained functions. No functional change beyond the removal of the old constructors are intended. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209082 91177308-0d34-0410-b5e6-96231b3b80d8
* Target: add support to build CallLoweringInfoSaleem Abdulrasool2014-05-17
| | | | | | | | | | | Rather than introducing an auxiliary CallLoweringInfoBuilder, add the methods to do chained function construction directly to CallLoweringInfo. This reduces the monstrous 15-parameter constructor into a series of simpler (for some definition of simpler) functions that control particular aspects of the call. The old interfaces can be completely removed once callers are moved to the new chained constructor pattern. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209081 91177308-0d34-0410-b5e6-96231b3b80d8
* Target: change member from reference to pointerSaleem Abdulrasool2014-05-17
| | | | | | | | | This is a preliminary step to help ease the construction of CallLoweringInfo. Changing the construction to a chained function pattern requires that the parameter be nullable. However, rather than copying the vector, save a pointer rather than the reference to permit a late binding of the arguments. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209080 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix most of PR10367.Rafael Espindola2014-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes the design of GlobalAlias so that it doesn't take a ConstantExpr anymore. It now points directly to a GlobalObject, but its type is independent of the aliasee type. To avoid changing all alias related tests in this patches, I kept the common syntax @foo = alias i32* @bar to mean the same as now. The cases that used to use cast now use the more general syntax @foo = alias i16, i32* @bar. Note that GlobalAlias now behaves a bit more like GlobalVariable. We know that its type is always a pointer, so we omit the '*'. For the bitcode, a nice surprise is that we were writing both identical types already, so the format change is minimal. Auto upgrade is handled by looking through the casts and no new fields are needed for now. New bitcode will simply have different types for Alias and Aliasee. One last interesting point in the patch is that replaceAllUsesWith becomes smart enough to avoid putting a ConstantExpr in the aliasee. This seems better than checking and updating every caller. A followup patch will delete getAliasedGlobal now that it is redundant. Another patch will add support for an explicit offset. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@209007 91177308-0d34-0410-b5e6-96231b3b80d8
* [yaml2obj][ELF] Add an optional `Size` field to the YAML section declaration.Simon Atanasyan2014-05-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now the only method to configure ELF section's content and size is to assign a hexadecimal string to the `Content` field. Unfortunately this way is completely useless when you need to declare a really large section. To solve this problem this patch adds one more optional field `Size` to the `RawContentSection` structure. When yaml2obj generates an ELF file it uses the following algorithm: 1. If both `Content` and `Size` fields are missed create an empty section. 2. If only `Content` field is missed take section length from the `Size` field and fill the section by zero. 3. If only `Size` field is missed create a section using data from the `Content` field. 4. If both `Content` and `Size` fields are provided validate that the `Size` value is not less than size of `Content` data. Than take section length from the `Size`, fill beginning of the section by `Content` and the rest by zero. Examples -------- * Create a section 0x10000 bytes long filled by zero Name: .data Type: SHT_PROGBITS Flags: [ SHF_ALLOC ] Size: 0x10000 * Create a section 0x10000 bytes long starting from 'CA' 'FE' 'BA' 'BE' Name: .data Type: SHT_PROGBITS Flags: [ SHF_ALLOC ] Content: CAFEBABE Size: 0x10000 The patch reviewed by Michael Spencer. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208995 91177308-0d34-0410-b5e6-96231b3b80d8

* Revert "Implement global merge optimization for global variables."Rafael Espindola2014-05-16
| | | | | | | | | | | | This reverts commit r208934. The patch depends on aliases to GEPs with non zero offsets. That is not supported and fairly broken. The good news is that GlobalAlias is being redesigned and will have support for offsets, so this patch should be a nice match for it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208978 91177308-0d34-0410-b5e6-96231b3b80d8
* Add C API for thread yielding callback.Juergen Ributzka2014-05-16
| | | | | | | | | | | | | | | | | | | | | Sometimes a LLVM compilation may take more time then a client would like to wait for. The problem is that it is not possible to safely suspend the LLVM thread from the outside. When the timing is bad it might be possible that the LLVM thread holds a global mutex and this would block any progress in any other thread. This commit adds a new yield callback function that can be registered with a context. LLVM will try to yield by calling this callback function, but there is no guaranteed frequency. LLVM will only do so if it can guarantee that suspending the thread won't block any forward progress in other LLVM contexts in the same process. Once the client receives the call back it can suspend the thread safely and resume it at another time.

* ProfileData: Allow multiple profiles in RawInstrProfReaderJustin Bogner2014-05-16
| | | | | | | | | | | | | | | | | | | Allow multiple raw profiles to coexist in a single .profraw file, given the following conditions: - Zero padding at the end of or between profiles will be skipped. - Each profile must start with a valid header. - Mixing endianness or pointer sizes in concatenated profiles files is not allowed. This is needed to handle cases where a program's shared libraries are profiled as well as the main executable itself, as we'll need to emit each executable's counters. Combining the tables in the runtime would be expensive for the instrumented program. rdar://16918688 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208938 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | | | | | | | | | | | | This was reverted in r208642 due to regressions surrounding file changes within lexical scopes causing inlining information to be lost. The issue was in LexicalScopes::getOrCreateInlinedScope, where I was previously testing "isLexicalBlock" which is false for "DILexicalBlockFile" (a scope used to represent changes in the current file name) and assuming it was then a function (breaking out of the inlined scope path and reaching for the parent non-inlined scopes). By inverting the condition and testing for "isSubprogram" the correct behavior is attained. (also found some weirdness in Clang, see r208742 when reducing this test case - the resulting test case doesn't apply with the Clang fix, but I've added a more realistic test case to inline-scopes.ll which does reproduce the issue and demonstrate the fix) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@208748 91177308-0d34-0410-b5e6-96231b3b80d8
