2012-12-03Use the new script to sort the includes of every file under lib.Chandler Carruth
Sooooo many of these had incorrect or strange main module includes. I have manually inspected all of these, and fixed the main module include to be the nearest plausible thing I could find. If you own or care about any of these source files, I encourage you to take some time and check that these edits were sensible. I can't have broken anything (I strictly added headers, and reordered them, never removed), but they may not be the headers you'd really like to identify as containing the API being implemented. Many forward declarations and missing includes were added to a header files to allow them to parse cleanly when included first. The main module rule does in fact have its merits. =] git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@169131 91177308-0d34-0410-b5e6-96231b3b80d8

The problem is that we are using ESP as the stack pointer in X86ISelLowering and RSP as the stack pointer in X86FrameLowering, and that revision made them both consistently use X86RegisterInfo to determine which to use.

2012-10-30[inline asm] Implement mayLoad and mayStore for inline assembly. In general,Chad Rosier
the MachineInstr MayLoad/MayLoad flags are based on the tablegen implementation. For inline assembly, however, we need to compute these based on the constraints.

2012-10-19This patch is to fix radar://8426430. It is about llvm support of ↵Shuxin Yang
__builtin_debugtrap() which is supposed to consistently raise SIGTRAP across all systems. In contrast, __builtin_trap() behave differently on different systems. e.g. it raises SIGTRAP on ARM, and SIGILL on X86. The purpose of __builtin_debugtrap() is to consistently provide "trap" functionality, in the mean time preserve the compatibility with on gcc on __builtin_trap(). The X86 backend is already able to handle debugtrap(). This patch is to: 1) make front-end recognize "__builtin_debugtrap()" (emboddied in the one-line change to Clang). 2) In DAG legalization phase, by default, "debugtrap" will be replaced with "trap", which make the __builtin_debugtrap() "available" to all existing ports without the hassle of changing their code. 3) If trap-function is specified (via -trap-func=xyz to llc), both __builtin_debugtrap() and __builtin_trap() will be expanded into the function call of the specified trap function. This behavior may need change in the future. The provided testing-case is to make sure 2) and 3) are working for ARM port, and we already have a testing case for x86. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@166300 91177308-0d34-0410-b5e6-96231b3b80d8

2012-10-10Issue description:Stepan Dyatkovskiy
SchedulerDAGInstrs::buildSchedGraph ignores dependencies between FixedStack objects and byval parameters. So loading byval parameters from stack may be inserted *before* it will be stored, since these operations are treated as independent. Fix: Currently ARMTargetLowering::LowerFormalArguments saves byval registers with FixedStack MachinePointerInfo. To fix the problem we need to store byval registers with MachinePointerInfo referenced to first the "byval" parameter. Also commit adds two new fields to the InputArg structure: Function's argument index and InputArg's part offset in bytes relative to the start position of Function's argument. E.g.: If function's argument is 128 bit width and it was splitted onto 32 bit regs, then we got 4 InputArg structs with same arg index, but different offset values. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@165616 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-25TargetLowering interface to set/get minimum block entries for jump tables.Sebastian Pop
Provide interface in TargetLowering to set or get the minimum number of basic blocks whereby jump tables are generated for switch statements rather than an if sequence. getMinimumJumpTableEntries() defaults to 4. setMinimumJumpTableEntries() allows target configuration.
