* Last minor cleanups, this code still does not work for all cases, but itChris Lattner2002-05-092-36/+20
| | | | | | | works much better than it used to. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2588 91177308-0d34-0410-b5e6-96231b3b80d8
* Two Cleanups to generated C code:Chris Lattner2002-05-092-70/+130
| | | | | | | | | | | | | | | 1. Avoid printing *(&globalvariable), instead print globalvariable alone as a special case. 2. Inline subexpressions into expressions as much as legal that preserves execution characteristics of expressions. Now we get nice (but over-parenthesized, oh well) things like: ltmp_428_7 = spec__putc(((unsigned char )((bsBuff) >> 24)), (bsStream)); instead of five seperate instructions (bsBuff & bsStream are globals). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2587 91177308-0d34-0410-b5e6-96231b3b80d8
* * Remove CInstPrintVisitor class, incorporating it into the CWriter classChris Lattner2002-05-092-688/+600
| | | | | | | * Reorder code in the file to make it more logically laid out. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2586 91177308-0d34-0410-b5e6-96231b3b80d8
* Remove CLocalVars data structure entirely, instead of building stuff andChris Lattner2002-05-092-56/+6
| | | | | | | then printing it out, just print as we go. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2585 91177308-0d34-0410-b5e6-96231b3b80d8

* * Clean up how PHI nodes are handledChris Lattner2002-05-092-108/+146
| | | | | | | | | | | | | | | * Correct global variable references * Fix loads & stores with zero indices * Do not emit an else part of a branch if there is no code (no phi node and a fallthrough branch), makes code more readable to get: if (l2_cond240) { goto l13_bb10; } with no else{} branch git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2583 91177308-0d34-0410-b5e6-96231b3b80d8

* * Remove dead "constant printing" codeChris Lattner2002-05-092-96/+44
| | | | | | | | | | * Mangle names with only a prefix so that they are easier on the eyes. * Put spaces around binary operators with low precedence to make them easier to read * Don't prefix function names with &, although it's correct, it's unnecesary and easier to read without it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2575 91177308-0d34-0410-b5e6-96231b3b80d8

* * Remove dead functionChris Lattner2002-05-092-18/+40
| | | | | | | | * Print C strings correctly * Expand C escape sequences nicely (ie \n \t, etc get generated instead of hex escapes) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2572 91177308-0d34-0410-b5e6-96231b3b80d8

* Incorporate and purge function before and after printing them so unnamed valuesChris Lattner2002-05-092-22/+32
| | | | | | | | | have some hope of working right. Function calls do not try to emit an lvalue if they return void. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2569 91177308-0d34-0410-b5e6-96231b3b80d8
* Factor out the code to print a value to ONE place.Chris Lattner2002-05-092-374/+202
| | | | | | | It turns out that unnamed values DO NOT work at all, that's next on the list. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@2568 91177308-0d34-0410-b5e6-96231b3b80d8
