2011-04-29Rename profile_rt.so to libprofile_rt.so under configure+make (it already wasNick Lewycky
under cmake). Add libprofile_rt.a so that we can tell clang to link against it in --coverage mode. Also turn it on by default in cmake builds. Oscar, this touches a change you made for EXCLUDE_FROM_ALL support -- I think I've done the right thing, but please let me know (or fix and commit) if not! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130470 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-28We require threse bits to be zero, too.Benjamin Kramer
This shouldn't happen in practice because the icmp would be a constant. Add a check so we don't miscompile code if something goes wrong. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130446 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-28Only read *predecessor once so as to fix a theoretical issue where it changesNick Lewycky
between two reads (threading). Fix an off-by-one in the indirect counter table that I meant to revert after an earlier experiment. Whoops! Implement GCOV_PREFIX. Doesn't handle GCOV_PREFIX_STRIP yet. Fix an off-by-one in string emission. Extra whoops! Tolerate DISubprograms that have null Function*'s attached to them. I don't yet understand what this means, but it happens when you have a global static with a non-trivial constructor/destructor. Fix a crash on switch statements with a single successor (default-only). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130443 91177308-0d34-0410-b5e6-96231b3b80d8

and it is just as easy to use StringRef::substr() preceding StringRef::compare() to achieve the same thing. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130430 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-28final step needed to resolve PR6627, which allows us to flatten the code down toChris Lattner
a nice and tidy: %x1 = load i32* %0, align 4 %1 = icmp eq i32 %x1, 1179403647 br i1 %1, label %if.then, label %if.end instead of doing lots of loads and branches.

2011-04-28Fix a bug in tblgen that caused incorrect encodings on instructions that ↵Owen Anderson
specified operands with "bit" instead of "bits<1>". Unfortunately, my only testcase for this is fragile, and the ARM AsmParser can't round trip the instruction in question. <rdar://problem/9345702> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130410 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-28Add command line option to print debug info in human readable form as ↵Devang Patel
comment in llvm IR output. This, i.e -enable-debug-info-comment, is very useful if you want to easily find out which optimization pass is losing line number information. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130409 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-28Fix the last -Wnon-pod-memset I'm seeing. This is benign, but appearsChandler Carruth
a bit more sinister as the memset doesn't do what the constructor does. There seems to be a cleaner solution than a cast here though, instead we can point the memset destination into the union its actually trying to clear. An alternative is to point to the Untyped member of this union. Review appreciated, and if that is cleaner I'm happy to switch. All of these should be functionally equivalent to the original code. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130395 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-28teach GVN to widen integer loads when they are overaligned, when doing an Chris Lattner
wider load would allow elimination of subsequent loads, and when the wider load is still a native integer type. This eliminates a ton of loads on various benchmarks involving struct fields, though it is somewhat hobbled by clang not being very aggressive about field alignment. This is yet another step along the way towards resolving PR6627. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130390 91177308-0d34-0410-b5e6-96231b3b80d8
