2011-05-02In option typo correction, consider -foo=VALUE flags as two distinct parts. TheNick Lewycky
comments claimed it did this, but the LHS value was actually an unused variable. The new system considers only the '-foo' part when comparing it for typos against flags that have values, but still look at the whole string for flags that don't. That way, we'll still correct '-inst=combine' to '-instcombine'. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130685 91177308-0d34-0410-b5e6-96231b3b80d8

2011-04-05Added *hidden* flags -print-options and -print-all-options soAndrew Trick
developers can see if their driver changed any cl::Option's. The current implementation isn't perfect but handles most kinds of options. This is nice to have when decomposing the stages of compilation and moving between different drivers. It's also a good sanity check when comparing results produced by different command line invocations that are expected to produce the comparable results. Note: This is not an attempt to prolong the life of cl::Option. On the contrary, it's a placeholder for a feature that must exist when cl::Option is replaced by a more appropriate framework. A new framework needs: a central option registry, dynamic name lookup, non-global containers of option values (e.g. per-module, per-function), *and* the ability to print options values and their defaults at any point during compilation. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128910 91177308-0d34-0410-b5e6-96231b3b80d8
2011-04-03Assorted bugfixes in object file handling:Eric Christopher
- Adds support for sniffing PE/COFF files on win32 (.exe and .dll) which are COFF files that have an MS-DOS compatibility stub on the front of them. - Fixes a bug in the COFFObjectFile's support for the Microsoft COFF extension for long symbol names, wherein it was attempting to parse the leading '/' in an extended symbol name reference as part of the integer offset. - Fixes bugs in COFFObjectFile and ELFObjectFile wherein section and symbol iterators were being returned with uninitialized bytes; the type DataRefImpl is a union between 2 32-bit words (d.a and d.b) and a single intptr_t word (p). Only p was being initialized, so in 32-bit builds the result would be iterators with random upper 32-bit words in their DataRefImpls. This caused random failures when seeking around in object files. Patch by Graydon Hoare! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128799 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-30Reset StringMap's NumTombstones on clears and rehashes.Jakob Stoklund Olesen
StringMap was not properly updating NumTombstones after a clear or rehash. This was not fatal until now because the table was growing faster than NumTombstones could, but with the previous change of preventing infinite growth of the table the invariant (NumItems + NumTombstones <= NumBuckets) stopped being observed, causing infinite loops in certain situations.

2011-03-30Avoid turning a floating point division with a constant power of two into a ↵Benjamin Kramer
denormal multiplication. Some platforms may treat denormals as zero, on other platforms multiplication with a subnormal is slower than dividing by a normal. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128555 91177308-0d34-0410-b5e6-96231b3b80d8
2011-03-30Add APFloat::getExactInverse.Benjamin Kramer
The idea is, that if an ieee 754 float is divided by a power of two, we can turn the division into a cheaper multiplication. This function sees if we can get an exact multiplicative inverse for a divisor and returns it if possible. This is the hard part of PR9587. I tested many inputs against llvm-gcc's frotend implementation of this optimization and didn't find any difference. However, floating point is the land of weird edge cases, so any review would be appreciated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@128545 91177308-0d34-0410-b5e6-96231b3b80d8
