* Rework dominator interfaces to handle changes in the post-dominanceChris Lattner2003-09-101-28/+47
| | | | | | | construction. Now there may be multiple root blocks, and null is a special node used to mark the "virtual" exit node of a CFG. llvm-svn: 8461
* Rework post dominator information so that we do not have toChris Lattner2003-09-101-88/+97
| | | | | | | | | unify all exit nodes of a function to compute post-dominance information. This does not work with functions that have both unwind and return nodes, because we cannot unify these blocks. The new implementation is better anyway. :) llvm-svn: 8460

* Simplification of trip counting machinery.Chris Lattner2003-09-101-73/+68
| | | | | | | | | | - make sure to check the indvar type before anything else (efficiency) - Make sure to insert the 'add' into the program, even though it'll be dead - Wrap code at 80 columns - Other minor cleanups to reduce indentation level llvm-svn: 8434
* Don't explicitly use $SourceDir to find the tblgen files. This causes makeJohn Criswell2003-09-101-4/+4
| | | | | | | | | | | | some confusion when trying to generate files (it probably couldn't tell that ./file and $(SourceDir)/file may be the same file). Now, just let VPATH find everything, and list the primary tblgen file first in the list of dependencies so that we can just use $< to reference it in the make rule. This should hopefully fix the nightly tester. llvm-svn: 8433

* Updated to find source files using VPATH. This makes writing build rulesJohn Criswell2003-09-094-33/+40
| | | | | | | | | | | much cleaner and easier. Labeled .td as a suffix for tblgen files in Makefile.rules. Modified build rules so that source files generated during the build are placed in the build directory and not the source directory (and not in a Debug directory). This makes the system cleaner and allows us to have a read-only source tree. llvm-svn: 8424

* Reverting back to the previous revision.John Criswell2003-09-091-1/+1
| | | | | | | | | | We want to check for length 5 because we might get the "llvm." string as the name. That string is in the LLVM namespace and should be checked as such. We also don't have to worry about garbage data because (I believe) the string class will return a valid value. So, the switch statement will work and we don't have to worry about the code wandering into segfault land. llvm-svn: 8419
* Modified the check for intrinsic functions. All intrinsic functions have toJohn Criswell2003-09-091-1/+1
| | | | | | | | be at least 6 characters, since something must follow the "llvm." string in the function name. This seems to fix an assertion failure with the SingleSource tests, too. llvm-svn: 8418
* * Simplify printConstantValueOnly by moving the tail padding stuff directlyChris Lattner2003-09-091-65/+90
| | | | | | | | | into the struct case. * Extend printConstantValueOnly to print .zero's if the initializer is zero * Delete dead isConstantFunctionPointerRef function * Emit the appropriate assembly for the various linkage types! llvm-svn: 8417
* Updated the log of changes (as required by the Burg copyright) to give anJohn Criswell2003-09-091-0/+8
| | | | | | | overview of what we changed (which is probably all that the author was looking for). llvm-svn: 8416
* Modified the code so that we exit() with a non-zero value instead of callingJohn Criswell2003-09-091-1/+1
| | | | | | | | abort() when we can't open the input filename. The abort() function generates a core dump if possible and is meant for handling errors so grand that even the program knows that debugging is necessary. llvm-svn: 8415
* Added the .t implicit rule. You can now run an individual set of QMTests byJohn Criswell2003-09-081-4/+2
| | | | | | | | specifying "make <test>.t" For example, make feature.t will run the feature tests. Removed the QMTESTS variable since it is no longer used. llvm-svn: 8414
