2004-10-04Move the warning about no compression library down to the bottom, awayReid Spencer
from the fray, so it gets noticed. This commit is made without the corresponding configure script commit because it doesn't affect functionality and we don't want to force everyone into another reconfigure git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16657 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-04Excise the ill-advised RLCOMP compression algorithm and simply leave theReid Spencer
previously temporary NULLCOMP implementation that merely copies the data verbatim without compression. Also, don't warn if there's no compression library as that is taken care of during configuration time. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16654 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-04First version of the MappedFile abstraction for operating system idependentReid Spencer
mapping of files. This first version uses mmap where its available. The class needs to implement an alternate mechanism based on malloc'd memory and file reading/writing for platforms without virtual memory. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16649 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04First version of a support utility to provide generalized compression inReid Spencer
LLVM that handles availability and unavailability of bzip2 and zlib. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16648 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04* Prune #includesChris Lattner

2004-10-04Add support for emitting AT&T style .s files, and make it the default. UsersChris Lattner
may now choose their output format with the -x86-asm-syntax={intel|att} flag. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16646 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04Convert some missed patterns to support AT&T styleChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16645 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04Apparently the GNU assembler has a HUGE hack to be compatible with reallyChris Lattner
old and broken AT&T syntax assemblers. The problem with this hack is that *SOME* forms of the fdiv and fsub instructions have the 'r' bit inverted. This was a real pain to figure out, but is trivially easy to support: thus we are now bug compatible with gas and gcc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16644 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04Provide support for auto-detection and use of compression libraries.Reid Spencer
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16643 91177308-0d34-0410-b5e6-96231b3b80d8

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16641 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-04Add missing suffixes to FP instructions for AT&T modeChris Lattner
git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16640 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-03Add support for the -x86-asm-syntax flag, which can be used to choose betweenChris Lattner
Intel and AT&T style assembly language. The ultimate goal of this is to eliminate the GasBugWorkaroundEmitter class, but for now AT&T style emission is not fully operational. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16639 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-03Add support to the instruction patterns for AT&T style output, which willChris Lattner
hopefully lead to the death of the 'GasBugWorkaroundEmitter'. This also includes changes to wrap the whole file to 80 columns! Woot! :) Note that the AT&T style output has not been tested at all. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16638 91177308-0d34-0410-b5e6-96231b3b80d8

lib/System and the compressing llvm archiver. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16634 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-01When a virtual register is folded into an instruction, keep track of whetherChris Lattner
it was a use, def, or both. This allows us to be less pessimistic in our analysis of them. In practice, this doesn't make a big difference, but it doesn't hurt either. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16632 91177308-0d34-0410-b5e6-96231b3b80d8

2004-10-01Add a simple little improvement to the local spiller to keep track of storesChris Lattner
and delete them if they turn out to be dead. This is a useful little hack that even speeds up some programs. For example, it speeds up Ptrdist/ks from 17.53s to 15.59s, and 188.ammp from 149s to 146s. This also speeds up llc :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@16630 91177308-0d34-0410-b5e6-96231b3b80d8
2004-10-01Substantially revamp the local spiller, causing it to actually improve theChris Lattner
generated code over the simple spiller. The new local spiller generates substantially better code than the simple one in some cases, by reusing values that are loaded out of stack slots and kept available in registers. This primarily helps programs that are spilling a lot, and there is still stuff that can be done to improve it. This patch makes the local spiller the default, as it's only a tiny bit slower than the simple spiller (it increases the runtime of llc by < 1%). Here are some numbers with speedups.
