2012-07-18This patch fixes 8 out of 20 unexpected failures in "make check"Preston Gurd
when run on an Intel Atom processor. The failures have arisen due to changes elsewhere in the trunk over the past 8 weeks or so. These failures were not detected by the Atom buildbot because the CPU on the Atom buildbot was not being detected as an Atom CPU. The fix for this problem is in Host.cpp and X86Subtarget.cpp, but shall remain commented out until the current set of Atom test failures are fixed.

2012-06-20Don't assert when given an empty range.Kaelyn Uhrain
llvm::RawMemoryObject handles empty ranges just fine, and the assert can be triggered in the wild by e.g. invoking clang with a file that included an empty pre-compiled header file when clang has been built with assertions enabled. Without assertions enabled, clang will properly report that the empty file is not a valid PCH. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158769 91177308-0d34-0410-b5e6-96231b3b80d8
2012-06-19Fix PR13148, an inf-loop in StringMap.Chandler Carruth
StringMap suffered from the same bug as DenseMap: when you explicitly construct it with a small number of buckets, you can arrange for the tombstone-based growth path to be followed when the number of buckets was less than '8'. In that case, even with a full map, it would compare '0' as not less than '0', and refuse to grow the table, leading to inf-loops trying to find an empty bucket on the next insertion. The fix is very simple: use '<=' as the comparison. The same fix was applied to DenseMap as well during its recent refactoring. Thanks to Alex Bolz for the great report and test case. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158725 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-16Harden the Unix signals code to be more async signal safe.Chandler Carruth
This is likely only the tip of the ice berg, but this particular bug caused any double-free on a glibc system to turn into a deadlock! It is not generally safe to either allocate or release heap memory from within the signal handler. The 'pop_back()' in RemoveFilesToRemove was deleting memory and causing the deadlock. What's worse, eraseFromDisk in PathV1 has lots of allocation and deallocation paths. We even passed 'true' in a place that would have caused the *signal handler* to try to run the 'system' system call and shell out to 'rm -rf'. That was never going to work... This patch switches the file removal to use a vector of strings so that the exact text needed for the 'unlink' system call can be stored there. It switches the loop to be a boring indexed loop, and directly calls unlink without looking at the error. It also works quite hard to ensure that calling 'c_str()' is safe, by ensuring that the non-signal-handling code path that manipulates the vector always leaves it in a state where every element has already had 'c_str()' called at least once. I dunno exactly how overkill this is, but it fixes the deadlock-on-double free issue, and seems likely to prevent any other issues from sneaking up. Sorry for not having a test case, but I *really* don't know how to test signal handling code easily.... git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@158580 91177308-0d34-0410-b5e6-96231b3b80d8

2012-06-02Use access(2) instead of stat(2) to check if a file exists.Benjamin Kramer
Apart from being slightly cheaper, this fixes a real bug that hits 32 bit linux systems. When passing a file larger than 2G to be linked (which isn't that uncommon with large projects such as WebKit), clang's driver checks if the file exists but the file size doesn't fit in an off_t and stat(2) fails with EOVERFLOW. Clang then says that the file doesn't exist instead of passing it to the linker. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@157891 91177308-0d34-0410-b5e6-96231b3b80d8
