Vikram S. Adve 4e537b27d8 Added subclass ConstantExpr to represent expressions consructed from 
constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.

Vikram S. Adve 8aee7962aa Create a static version of Instruction::getOpcodeName(opCode) that 
can be invoked with only an opcode (i.e., without an instruction).
Move all opCode->opCodeName translations there.

Vikram S. Adve c1b6474a60 Write out the plane for types first, since values of primitive types 
may be constructed by expressions of other types (and so the
contents of the primitive type planes must come after all types).
Use a helper function outputConstantsInPlane in outputConstants to
do this.

Vikram S. Adve a336afd5d9 Add support for reading ConstantExpr nodes. 
Add class ConstantFwdRefs to resolve forward references to constants
and to globals. (Hmm... this class could be renamed I guess.)

Vikram S. Adve 16bcca5ee4 Add support for reading ConstantExpr nodes.

Vikram S. Adve 7064eaf80b Added support for parsing expressions constructed from constant values.

Vikram S. Adve 83500260ae Added subclass ConstantExpr to represent expressions consructed from 
constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.   This is why isConstantExpr() is needed.

llvm-svn: 2891
 2002-07-14 22:47:54 +00:00
Vikram S. Adve eacabece8d Add a couple of virtual functions to support subclass ConstantExpr. 
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.   This is why isConstantExpr() is needed.

Chris Lattner fdbd7241c9 New implementation of data structure analysis

implementation.

llvm-svn: 2872
 2002-07-10 22:42:17 +00:00
Chris Lattner c0dab43c31 New implementation of data structure analysis. Only local analysis has been

Vikram S. Adve 2a5085af8c Include Makefile.singlesrc in order to compile .c tests. 
Some of these are not regression tests and this directory needs
to be reorganized, but the tests are important.

llvm-svn: 2866
 2002-07-10 22:02:37 +00:00
Vikram S. Adve 253d9e40a2 Some of these are feature tests, not regression tests. 
This directory needs to be reorganized and some of the tests
need changes to make them executable.  Also comments would help...

llvm-svn: 2857
 2002-07-10 21:41:21 +00:00
Vikram S. Adve 58c904ace6 Major overhaul to stop using pseudo-instructions (SETX, SETUW, SETSW) 
and generate actual machine instruction sequences directly.

Also a couple of bug fixes in code for putting constants into registers:
-- Do *not* sign-extend unsigned constant that is shorter than int reg size
-- Fix handling of address constant (a GlobalValue) vs. constant that
   must be loaded.

llvm-svn: 2856
 2002-07-10 21:39:50 +00:00
Vikram S. Adve 4aee77c70b More important fixes: 
-- FP argument to a function with no prototype going on stack
   was not being copied to the stack in colorCallArgs().
-- Put caller-saving code *before* argument copying code so that
   we don't trash a register before saving it!
-- Two other minor fixes.

llvm-svn: 2855
 2002-07-10 21:36:00 +00:00
Vikram S. Adve 9423a4d0a5 Put caller-saving code *before* argument copying code!
