* [bugpoint] Increase the default memory limit for subprocesses to 300MB.Daniel Sanders2013-10-251-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Summary: Currently shared library builds (BUILD_SHARED_LIBS=ON in cmake) fail three bugpoint tests (BugPoint/remove_arguments_test.ll, BugPoint/crash-narrowfunctiontest.ll, and BugPoint/metadata.ll). If I run the bugpoint commands that llvm-lit runs with without -silence-passes I see errors such as this: opt: error while loading shared libraries: libLLVMSystemZInfo.so: failed to map segment from shared object: Cannot allocate memory It seems that the increased size of the binaries in a shared library build is causing the subprocess to exceed the 100MB memory limit. This patch therefore increases the default limit to a level at which these tests pass.

| | | | | | | | | | | | This fix a memory leak found by valgrind. Calling it from the base class destructor would not destroy the BasicCallGraph bits.

* ARM: allow .thumb_func to be separated from symbol definitionTim Northover2013-10-254-18/+23
| | | | | | | | | | When assembling, a .thumb_func directive is supposed to be applicable to the next symbol definition, even if there are intervening directives. We were racing ahead to try and find it, and this commit should fix the issue.

* ARM: don't expand atomicrmw inline on Cortex-M0Tim Northover2013-10-253-9/+14
| | | | | | | | | | There's a barrier instruction so that should still be used, but most actual atomic operations are going to need a platform decision on the correct behaviour (either nop if single-threaded or OS-support otherwise). rdar://problem/15287210 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193399 91177308-0d34-0410-b5e6-96231b3b80d8
* LegalizeDAG: allow libcalls for max/min atomic operationsTim Northover2013-10-254-0/+104
| | | | | | | | | | | ARM processors without ldrex/strex need to be able to make libcalls for all atomic operations, including the newer min/max versions. The alternative would probably be expanding these operations in terms of cmpxchg (as x86 does always), but in the configurations where this matters code-size tends to be paramount so the libcall is more desirable. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193398 91177308-0d34-0410-b5e6-96231b3b80d8

* Support for reading program counts in llvm-cov.Yuchen Wu2013-10-252-13/+34
| | | | | | | | | | | | | llvm-cov will now be able to read program counts from the GCDA file and output it in the same format as gcov. The program summary tag was identified from gcov-io.h as "\0\0\0\a3". There is currently a bug in GCOVProfiling.cpp which does not generate the run- or program-counting IR, so this change was tested manually by modifying the GCDA file and comparing the gcov and llvm-cov outputs. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193389 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | The fused multiply instructions were added in VFPv4 but are still NEON instructions, in particular they shouldn't be available on a Cortex-M4 not matter how floaty it is. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193342 91177308-0d34-0410-b5e6-96231b3b80d8

* ARM: Use non-VFP softcalls on embedded Darwinish targetsTim Northover2013-10-242-1/+23
| | | | | | | | | | | | | The compiler-rt functions __adddf3vfp and so on exist purely to allow Thumb1 code to make use of VFP instructions by switching back to ARM mode, they make no sense for M-class processors which don't even have an ARM mode. Given that justification, in practice this is a platform ABI decision so the actual check is based on that rather than CPU features. rdar://problem/15302004 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@193327 91177308-0d34-0410-b5e6-96231b3b80d8
