* For PR786:Reid Spencer2006-11-021-1/+0
| | | | | | | | | | | Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting fall out by removing unused variables. Remaining warnings have to do with unused functions (I didn't want to delete code without review) and unused variables in generated code. Maintainers should clean up the remaining issues when they see them. All changes pass DejaGnu tests and Olden. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31380 91177308-0d34-0410-b5e6-96231b3b80d8
* Refactor a bunch of includes so that TargetMachine.h doesn't have to includeOwen Anderson2006-05-121-0/+1
| | | | | | | | TargetData.h. This should make recompiles a bit faster with my current TargetData tinkering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28238 91177308-0d34-0410-b5e6-96231b3b80d8
* Suck block address tracking out of targets into the JIT Emitter. ThisChris Lattner2006-05-031-6/+9
| | | | | | | | simplifies the MachineCodeEmitter interface just a little bit and makes BasicBlocks work like constant pools and jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28082 91177308-0d34-0410-b5e6-96231b3b80d8
* Refactor TargetMachine, pushing handling of TargetData into the ↵Owen Anderson2006-05-031-4/+4

* Several related changes:Chris Lattner2006-05-021-4/+6
| | | | | | | | | | | | | | 1. Change several methods in the MachineCodeEmitter class to be pure virtual. 2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them from the MachineCodeEmitter interface, and reducing the amount of target- specific code. 3. Change the JITEmitter so that it allocates constantpools and jump tables *right* next to the functions that they belong to, instead of in a separate pool of memory. This makes all memory for a function be contiguous, and means the JITEmitter only tracks one block of memory now. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28065 91177308-0d34-0410-b5e6-96231b3b80d8
* Do not make the JIT memory manager manage the memory for globals. InsteadChris Lattner2006-05-021-4/+0
| | | | | | | just have the JIT malloc them. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28062 91177308-0d34-0410-b5e6-96231b3b80d8
* Refactor the machine code emitter interface to pull the pointers for the currentChris Lattner2006-05-021-14/+7
| | | | | | | | | | | code emission location into the base class, instead of being in the derived classes. This change means that low-level methods like emitByte/emitWord now are no longer virtual (yaay for speed), and we now have a framework to support growable code segments. This implements feature request #1 of PR469. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28059 91177308-0d34-0410-b5e6-96231b3b80d8

| | | | | | | | | x86 and ppc for 100% dense switch statements when relocations are non-PIC. This support will be extended and enhanced in the coming days to support PIC, and less dense forms of jump tables. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@27947 91177308-0d34-0410-b5e6-96231b3b80d8

* Only get the .bss and .data sections when needed instead of unconditionally.Chris Lattner2005-07-161-11/+3
| | | | | | | This allows is to not emit empty sections when .data or .bss is not used. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22457 91177308-0d34-0410-b5e6-96231b3b80d8

* Major refactor of the ELFWriter code. Instead of building up one bigChris Lattner2005-07-161-143/+167
| | | | | | | | | | | | vector that represents the .o file at once, build up a vector for each section of the .o file. This is needed because the .o file writer needs to be able to switch between sections as it emits them (e.g. switch between the .text section and the .rel section when emitting code). This patch has no functionality change. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22453 91177308-0d34-0410-b5e6-96231b3b80d8

* add code to emit the .text section to the section header.Chris Lattner2005-07-111-4/+89
| | | | | | | | | | | | | | | | | | | | | | | | | | Add a *VERY INITIAL* machine code emitter class. This is enough to take this C function: int foo(int X) { return X +1; } and make objdump produce the following: $ objdump -d t-llvm.o t-llvm.o: file format elf32-i386 Disassembly of section .text: 00000000 <.text>: 0: b8 01 00 00 00 mov $0x1,%eax 5: 03 44 24 04 add 0x4(%esp,1),%eax 9: c3 ret Anything using branches or refering to the constant pool or requiring relocations will not work yet. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@22375 91177308-0d34-0410-b5e6-96231b3b80d8
