2004-01-12Use constantexprs for casts. Eliminate use of the ConstantHandling interfacesChris Lattner

2004-01-12Fix fairly severe bug in my last checking where we treated all unfoldableChris Lattner
constants as being "true" when evaluating branches. This was introduced because we now create constantexprs for the constants instead of failing the fold. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10778 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-12Modified the configure script so that it defines BISON as the bisonJohn Criswell
binary and YACC as bison -y. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10776 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-12The configure script now defines BISON as the name of the bison program andJohn Criswell
YACC as bison -y. In this way, we ensure that bison is being used, but the Makefiles have macros for using bison itself and for getting bison to act like it is traditional yacc. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10774 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-12* Implement minor performance optimization for the getelementptr caseChris Lattner
* Implement SCCP of load instructions, implementing Transforms/SCCP/loadtest.ll This allows us to fold expressions like "foo"[2], even if the pointer is only a conditional constant. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10767 91177308-0d34-0410-b5e6-96231b3b80d8

from constant memory is, but lets not take chances. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10765 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-12New testcase, allow folding of binary operators that use PHI nodes, as longChris Lattner
as the result of the binary operator is always constant. This does not require the PHI itself to be constant though. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10762 91177308-0d34-0410-b5e6-96231b3b80d8

case that the C/C++ front-end generates. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10761 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-11This isn't really an assembler test. This tests to make sure theChris Lattner
ConstantExpr::getGetElementPtr method folds two getelementptr instructions when possible. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10758 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-11Make LiveVariables::HandlePhysRegUse andAlkis Evlogimenos
LiveVariables::HandlePhysRegDef private they use information that is not in memory when LiveVariables finishes the analysis. Also update the TwoAddressInstructionPass to not use this interface. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10755 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-10Check in two changes:Chris Lattner
The first change (which is disabled) compactifies all of the function constant pools into the global constant pool, in an attempt to reduce the amount of duplication and overhead. Unfortunately, as the comment indicates, this is not yet a win, so it is disabled. The second change sorts the typeid's so that those types that can be used by instructions in the program appear earlier in the table than those that cannot (such as structures and arrays). This causes the instructions to be able to use the dense encoding more often, saving about 5K on 254.gap. This is only a .65% savings though, unfortunately. :( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10754 91177308-0d34-0410-b5e6-96231b3b80d8

2004-01-10Update obsolete commentsChris Lattner
Fix iterator invalidation problems which was causing -mstrip to miss some entries, and read free'd memory. This shrinks the symbol table of 254.gap from 333 to 284 bytes! :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10751 91177308-0d34-0410-b5e6-96231b3b80d8
2004-01-10Do not bother to emit a BytecodeBlock for an empty symbol table. This commonlyChris Lattner
occurs when the symbol table for a module has been stripped, making all of the function local symbols go away. This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously has 841 functions), which isn't a ton, but helps and was easy. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@10750 91177308-0d34-0410-b5e6-96231b3b80d8
