* Don't sink argument loads into loops or other bad places. This disables ↵Chris Lattner2005-02-171-1/+8
| | | | | | folding of argument loads with instructions that are not in the entry block. llvm-svn: 20228
* Do not mark obviously unreachable blocks live when processing PHI nodes,Chris Lattner2005-02-171-40/+61

* Remove the "pax" program from the list of those needed to support LLVM.Reid Spencer2005-02-163-82/+39
| | | | | | | The install target in Makefile.rules no longer uses pax but just uses find and "install" instead. llvm-svn: 20216
* Fix installation of configuration files.Reid Spencer2005-02-161-2/+2

| | | | | | | | * Make it possible to have the Install program run in verbose mode when the TOOL_VERBOSE=1 option is set * Ensure non-executable installed files do not install with execute perms. llvm-svn: 20214
* Don't use pax for installing header files. Use the install program instead.Reid Spencer2005-02-161-6/+8

* Instead of doing a manual comparison loop, just use memcmp, thanks to JohnCChris Lattner2005-02-151-9/+6
| | | | | | for the suggestion! :) llvm-svn: 20203
* Make this more efficient now that we know both files are the same length.Chris Lattner2005-02-151-2/+2

* Adjust DiffFilesWithTolerance to help poor cygwin's mmap facility byReid Spencer2005-02-151-8/+24
| | | | | | | | | | handling zero length files a little more intelligently. If both files are zero length then we return 0 (true) indicating a match. If only one of the files is zero length then we return 1 (false) indicating that the files differ. If the files don't agree in length then they can't match so we skip the first loop that looks for a quick match. llvm-svn: 20200
* add Alpha to llcAndrew Lenharth2005-02-151-0/+1

* Fix a problem where the PPC backend lost track of the fact that it hadChris Lattner2005-02-151-1/+3
| | | | | | | | to save and restore the LR register on entry and exit of a leaf function that needed to access globals or the constant pool. This should hopefully fix oscar from sending the PPC tester spinning out of control. llvm-svn: 20197
* Add a sanity check.Chris Lattner2005-02-151-0/+1
| | | | llvm-svn: 20195

* Fix volatile load/store of pointers. Consider this testcase:Chris Lattner2005-02-151-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | void %test(int** %P) { %A = volatile load int** %P ret void } void %test2(int*** %Q) { %P = load int*** %Q volatile store int** %P, int*** %Q ret void } instead of emitting: void test(int **l1_P) { int *l2_A; l2_A = (int **((volatile int **)l1_P)); return; } void test2(int ***l2_Q) { int **l1_P; l1_P = *l2_Q; *((volatile int ***)l2_Q) = l1_P; return; } ... which is loading/storing volatile pointers, not through volatile pointers, emit this (which is right): void test(int **l1_P) { int *l3_A; l3_A = *((int * volatile*)l1_P); return; } void test2(int ***l2_Q) { int **l1_P; l1_P = *l2_Q; *((int ** volatile*)l2_Q) = l1_P; return; } llvm-svn: 20191

* execution tests shouldn't go here. This was killing the PPC nightly tester.Chris Lattner2005-02-141-1/+1

* For PR496:Reid Spencer2005-02-141-2/+10
| | | | | | | | | | When llvm-gcc is not available, bypass rules for Modules and Bytecode Libraries that require llvm-gcc and emit instead a warning that llvm-gcc is not available. This permits "make LLVMGCC=" to build LLVM completely without error and provides warnings about the modules and bc libs that could not be constructed. llvm-svn: 20185
* Fix a bug in my previous change to this, which broke the build on sparcs.Chris Lattner2005-02-141-1/+1
| | | | llvm-svn: 20184
* Print GEP offsets as signed values instead of unsigned values. On X86, thisChris Lattner2005-02-141-3/+7
| | | | | | | | | | | | | | prints: getelementptr (int* %A, int -1) as: "(A) - 4" instead of "(A) + 18446744073709551612", which makes the assembler much happier. This fixes test/Regression/CodeGen/X86/2005-02-14-IllegalAssembler.ll, and Benchmarks/Prolangs-C/cdecl with LLC on X86. llvm-svn: 20183
* A testcase that LLC produces illegal asm on for Prolangs-C/cdecl now.Chris Lattner2005-02-141-0/+5
