* llvm-cov: Added -a option for block data.Yuchen Wu2013-12-10
| | | | | | | | | | | | | | | Similar to gcov, llvm-cov will now print out the block count at the end of each block. Multiple blocks can end on the same line. One computational difference is by using -a, llvm-cov will no longer simply add the block counts together to form a line count. Instead, it will take the maximum of the block counts on that line. This has a similar effect to what gcov does, but generates more correct counts in certain scenarios. Also updated tests. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196856 91177308-0d34-0410-b5e6-96231b3b80d8

* Improve the detection of the pathSylvestre Ledru2013-12-09
| | | | | | | | | | | | | | | | | | | | | | | | | Summary: When clang is used under GNU/Linux in a chroot without /proc mount, it falls back on the BSD method. However, since the buf variable is used twice and fails with snprintf to produce the correct path. When called as relatived (ie ./clang), it was failing with: "" -cc1 [...] -x c++ x.cc error: unable to execute command: Executable "" doesn't exist! I also took the opportunity to simply the code (the first arg of test_dir was useless).

The offset must therefore be a multiple of the element size to be valid in these instructions. However, an unaligned base address is valid in MSA. This commit causes the compiler to emit valid code when the calculated offset is not a multiple of the element size by accounting for the offset using addiu and using a zero offset in the load/store.

* Method parseSetAssignment treats every operand with '$' sign as register and ↵Vladimir Medic2013-12-09
| | | | | | | | | the parsing is directed to set alias for register. This will result in errors reported when expressions containing label references are parsed(for example long jumps) As we can't make a complete solution now it has been decided to enable .set directive to handle long jump expressions. This will cause parser to report errors when parsing integer based register assignments, for example: .set r3, will be reported as error. Still, the need for expressions is higher priority as the integer based register assignments are Mips specific and can be avoided using register names. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196773 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: fix folding of stack-adjustment (yet again).Tim Northover2013-12-08
| | | | | | | | | | | | | | | | | | | | | | When trying to eliminate an "sub sp, sp, #N" instruction by folding it into an existing push/pop using dummy registers, we need to account for the fact that this might affect precisely how "fp" gets set in the prologue. We were attempting this, but assuming that *whenever* we performed a fold it would make a difference. This is false, for example, in: push {r4, r7, lr} add fp, sp, #4 vpush {d8} sub sp, sp, #8 we can fold the "sub" into the "vpush", forming "vpush {d7, d8}". However, in that case the "add fp" instruction mustn't change, which we were getting wrong before. Should fix PR18160. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@196725 91177308-0d34-0410-b5e6-96231b3b80d8

* Fix inlining to not produce duplicate landingpad clausesMark Seaborn2013-12-08
| | | | | | | | | | | | | | | | | | | | | | | Before this change, inlining one "invoke" into an outer "invoke" call site can lead to the outer landingpad's catch/filter clauses being copied multiple times into the resulting landingpad. This happens: * when the inlined function contains multiple "resume" instructions, because forwardResume() copies the clauses but is called multiple times; * when the inlined function contains a "resume" and a "call", because HandleCallsInBlockInlinedThroughInvoke() copies the clauses but is redundant with forwardResume(). Fix this by deduplicating the code. This problem doesn't lead to any incorrect execution; it's only untidy.
