* Clean up a pile of hacks in our CMake build relating to TableGen.Chandler Carruth2011-07-262-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The first problem to fix is to stop creating synthetic *Table_gen targets next to all of the LLVM libraries. These had no real effect as CMake specifies that add_custom_command(OUTPUT ...) directives (what the 'tablegen(...)' stuff expands to) are implicitly added as dependencies to all the rules in that CMakeLists.txt. These synthetic rules started to cause problems as we started more and more heavily using tablegen files from *subdirectories* of the one where they were generated. Within those directories, the set of tablegen outputs was still available and so these synthetic rules added them as dependencies of those subdirectories. However, they were no longer properly associated with the custom command to generate them. Most of the time this "just worked" because something would get to the parent directory first, and run tablegen there. Once run, the files existed and the build proceeded happily. However, as more and more subdirectories have started using this, the probability of this failing to happen has increased. Recently with the MC refactorings, it became quite common for me when touching a large enough number of targets. To add insult to injury, several of the backends *tried* to fix this by adding explicit dependencies back to the parent directory's tablegen rules, but those dependencies didn't work as expected -- they weren't forming a linear chain, they were adding another thread in the race. This patch removes these synthetic rules completely, and adds a much simpler function to declare explicitly that a collection of tablegen'ed files are referenced by other libraries. From that, we can add explicit dependencies from the smaller libraries (such as every architectures Desc library) on this and correctly form a linear sequence. All of the backends are updated to use it, sometimes replacing the existing attempt at adding a dependency, sometimes adding a previously missing dependency edge. Please let me know if this causes any problems, but it fixes a rather persistent and problematic source of build flakiness on our end. llvm-svn: 136023

| | | | | | | | - Introduce JITDefault code model. This tells targets to set different default code model for JIT. This eliminates the ugly hack in TargetMachine where code model is changed after construction. llvm-svn: 135580

| | | | | | | | | | | | and MCSubtargetInfo. - Added methods to update subtarget features (used when targets automatically detect subtarget features or switch modes). - Teach X86Subtarget to update MCSubtargetInfo features bits since the MCSubtargetInfo layer can be shared with other modules. - These fixes .code 16 / .code 32 support since mode switch is updated in MCSubtargetInfo so MC code emitter can do the right thing. llvm-svn: 134884

| | | | | | | | | CPU, and feature string. Parsing some asm directives can change subtarget state (e.g. .code 16) and it must be reflected in other modules (e.g. MCCodeEmitter). That is, the MCSubtargetInfo instance must be shared. llvm-svn: 134795
* Add an intrinsic and codegen support for fused multiply-accumulate. The intentCameron Zwarich2011-07-081-0/+2

* Eliminate asm parser's dependency on TargetMachine:Evan Cheng2011-07-082-2/+3
| | | | | | | | | | - Each target asm parser now creates its own MCSubtatgetInfo (if needed). - Changed AssemblerPredicate to take subtarget features which tablegen uses to generate asm matcher subtarget feature queries. e.g. "ModeThumb,FeatureThumb2" is translated to "(Bits & ModeThumb) != 0 && (Bits & FeatureThumb2) != 0". llvm-svn: 134678

* Starting to refactor Target to separate out code that's needed to fully describeEvan Cheng2011-06-243-7/+9
| | | | | | | | | | | | target machine from those that are only needed by codegen. The goal is to sink the essential target description into MC layer so we can start building MC based tools without needing to link in the entire codegen. First step is to refactor TargetRegisterInfo. This patch added a base class MCRegisterInfo which TargetRegisterInfo is derived from. Changed TableGen to separate register description from the rest of the stuff. llvm-svn: 133782
* Use set operations instead of plain lists to enumerate register classes.Jakob Stoklund Olesen2011-06-151-18/+16
| | | | | | | | | | | | This simplifies many of the target description files since it is common for register classes to be related or contain sequences of numbered registers. I have verified that this doesn't change the files generated by TableGen for ARM and X86. It alters the allocation order of MBlaze GPR and Mips FGR32 registers, but I believe the change is benign. llvm-svn: 133105
* Remove custom allocation order boilerplate that is no longer needed.Jakob Stoklund Olesen2011-06-092-15/+3
| | | | | | | | | | | | | | | | | | | | The register allocators automatically filter out reserved registers and place the callee saved registers last in the allocation order, so custom methods are no longer necessary just for that. Some targets still use custom allocation orders: ARM/Thumb: The high registers are removed from GPR in thumb mode. The NEON allocation orders prefer to use non-VFP2 registers first. X86: The GR8 classes omit AH-DH in x86-64 mode to avoid REX trouble. SystemZ: Some of the allocation orders are omitting R12 aliases without explanation. I don't understand this target well enough to fix that. It looks like all the boilerplate could be removed by reserving the right registers. llvm-svn: 132781

| | | | | | | | | | | LiveIns." In other words, do not keep track of argument's location. The debugger (gdb) is not prepared to see line table entries for arguments. For the debugger, "second" line table entry marks beginning of function body. This requires some coordination with debugger to get this working. - The debugger needs to be aware of prolog_end attribute attached with line table entries. - The compiler needs to accurately mark prolog_end in line table entries (at -O0 and at -O1+) llvm-svn: 126155
