* Include cmath/math.h in DataTypes.h regardless of whether MSVC is being used.Stefanus Du Toit2009-07-282-12/+12
| | | | | | | | Fixes MSVC build of LiveInterval.cpp. Patch by Nicolas Capens. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77317 91177308-0d34-0410-b5e6-96231b3b80d8
* Rip all of the global variable lowering logic out of TargetAsmInfo. SinceChris Lattner2009-07-287-147/+203
| | | | | | | | | | | | | | | | | | | | | | | it is highly specific to the object file that will be generated in the end, this introduces a new TargetLoweringObjectFile interface that is implemented for each of ELF/MachO/COFF/Alpha/PIC16 and XCore. Though still is still a brutal and ugly refactoring, this is a major step towards goodness. This patch also: 1. fixes a bunch of dangling pointer problems in the PIC16 backend. 2. disables the TargetLowering copy ctor which PIC16 was accidentally using. 3. gets us closer to xcore having its own crazy target section flags and pic16 not having to shadow sections with its own objects. 4. fixes wierdness where ELF targets would set CStringSection but not CStringSection_. Factor the code better. 5. fixes some bugs in string lowering on ELF targets. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77294 91177308-0d34-0410-b5e6-96231b3b80d8

* Many of Daniel's fixes.Sean Callanan2009-07-271-15/+14
| | | | | | | | | | | | | | I'm returning the number of bytes actually copied so that the client has some warning when it reads past the end of the buffer. I'm keeping the distinction between getByte() and getBytes() for now for subclasses that use functions like ptrace() on Linux and only have a restricted interface. This makes their implementation easier, and subclasses can always write a one-line implementation of readByte() that uses their custom readBytes(). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77225 91177308-0d34-0410-b5e6-96231b3b80d8
