* 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
* 1. Clean up code due to changes in SwitchTo*Section(2)Anton Korobeynikov2006-10-311-4/+4
| | | | | | | | | | | 2. Added partial debug support for mingw\cygwin targets (the same as Linux\ELF). Please note, that currently mingw\cygwin uses 'stabs' format for storing debug info by default, thus many (runtime) libraries has this information included. These formats shouldn't be mixed in one binary ('stabs' & 'DWARF'), otherwise binutils tools will be confused. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@31311 91177308-0d34-0410-b5e6-96231b3b80d8

* Fixing truncate. Previously we were emitting truncate from r16 to r8 asEvan Cheng2006-05-081-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | movw. That is we promote the destination operand to r16. So %CH = TRUNC_R16_R8 %BP is emitted as movw %bp, %cx. This is incorrect. If %cl is live, it would be clobbered. Ideally we want to do the opposite, that is emitted it as movb ??, %ch But this is not possible since %bp does not have a r8 sub-register. We are now defining a new register class R16_ which is a subclass of R16 containing only those 16-bit registers that have r8 sub-registers (i.e. AX - DX). We isel the truncate to two instructions, a MOV16to16_ to copy the value to the R16_ class, followed by a TRUNC_R16_R8. Due to bug 770, the register colaescer is not going to coalesce between R16 and R16_. That will be fixed later so we can eliminate the MOV16to16_. Right now, it can only be eliminated if we are lucky that source and destination registers are the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28164 91177308-0d34-0410-b5e6-96231b3b80d8

* Better implementation of truncate. ISel matches it to a pseudo instructionEvan Cheng2006-05-051-101/+34

And if the destination gets allocated a subregister of the source operand, then the instruction will not be emitted at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@28119 91177308-0d34-0410-b5e6-96231b3b80d8
