| | | | | | | | | | 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.

* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8433 91177308-0d34-0410-b5e6-96231b3b80d8

* Updated to find source files using VPATH. This makes writing build rulesJohn Criswell2003-09-092-9/+18
| | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8424 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8419 91177308-0d34-0410-b5e6-96231b3b80d8
* 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@8418 91177308-0d34-0410-b5e6-96231b3b80d8
