* For PR1082:Reid Spencer2007-01-061-59/+118
| | | | | | | | | Solve several related problems by making variable names more unique and dealing with recursive phi nodes. Unfortunately, this doesn't solve the main issue reported in the PR, but its a step in that direction. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32953 91177308-0d34-0410-b5e6-96231b3b80d8
* For PR1080:Reid Spencer2007-01-061-2/+2
| | | | | | | | | Emit the correct syntax for icmp and fcmp constant expressions. The predicate goes outside the parentheses not inside. This was a change made in the assembler without the corresponding change made in llvm-upgrade. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32942 91177308-0d34-0410-b5e6-96231b3b80d8
* Major update of llvm-upgrade:Reid Spencer2007-01-051-118/+471
| | | | | | | | | | | | | | | | | | | | 1. Completely revise the type system so that types are handled as const objects and not created multiple times, cloned, or otherwise copied. This gets around memory issues, saves memory, and also emulates LLVM's no-two-types-of-the-same-shape-created semantics. 2. Adjust the handling of global names. Basically, we cannot rename them for a variety of reasons: linking, forward references, etc. 3. Detect global names that have name conflicts as the result of collapsed type planes or redefinitions that llvm-as no longer accepts. These will produce warnings on stderr and one of the globals will be renamed. 4. Rename ParserInternals.h as UpgradeInternals.h so it doesn't conflict in the debugger with ParserInternals.h from lib/AsmParser. 5. Move the guts of the TypeInfo class into the grammar so we aren't implementing large functions in a header file. This also helps with debugging a bit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32906 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR1070:Reid Spencer2007-01-021-283/+416
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Revise the upgrade parser to keep track of types more faithfully and use this information to resolve name conflicts resulting from collapsed type planes. The type planes have collapsed because the integer types are now signless so that uint and int became i32. Where two planes existed for uint and int, only i32 exists. Any variable names depending on the type planes to pmake the identifier unique would cause a conflict. This patch resolves that conflict for many but not all cases. Situations involving the integer types and pointers to them are handled by this patch. However, there are corner cases that are not handled well, such as: %t1 = type { uint, int } %t2 = type { int, uint } void %myfunc(%t1* one, %t2* two) { %var = load %t1* one %var = load %t2* two } In the scenario above, %t1 and %t2 are really the same type: { i32, i32 } Consequently attempting to name %var twice will yield a redefinition error when assembled. While this patch is sufficien to allow the llvm/test suite to pass, More work needs to be to complete the handling of these corner cases. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32810 91177308-0d34-0410-b5e6-96231b3b80d8

* For PR950:Reid Spencer2006-12-291-41/+63
| | | | | | | | | | | | Fix several bugs and update for new assembly syntax. Changes made include: 1. Fixing rules for icmp/fcmp instructions to not require a closing paren at the end. This was a cut-and-paste error from a previous commit. 2. Changing things like Out << " " to Out << ' ' 3. Adding the "define" keyword for function definitions 4. Adding support for packed structures git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@32771 91177308-0d34-0410-b5e6-96231b3b80d8
