depend on the compiler. This works around problems in the Stacker runtime
when the CFE changes in such a way that the assembly file needs to be
updated.
llvm-svn: 32773
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
llvm-svn: 32771
Remove all grammar conflicts from assembly parsing. This change involves:
1. Making the "type" keyword not a primitive type (removes several
reduce/reduce conflicts)
2. Being more specific about which linkage types are allowed for functions
and global variables. In particular "appending" can no longer be
specified for a function. A differentiation was made between the various
internal and external linkage types.
3. Introduced the "define" keyword which is now required when defining a
function. This disambiguates several cases where a named function return
type could get confused with the definition of a new type. Using the
keyword eliminates all shift/reduce conflicts and the remaining
reduce/reduce conflicts.
These changes are necessary to implement the function parameter attributes
that will be introduced soon. Adding the function parameter attributes in
the presence of the shift/reduce and reduce/reduce conflicts led to severe
ambiguities that caused the parser to report syntax errors that needed to
be resolved. This patch resolves them.

1. Make the arguments const like the other ConstantFold* functions.
2. Clean up evaluateFCmpRelation so it makes sense for floating point.
3. Implement the use of evaluateFCmpRelation to fold floating point CEs
4. Shorten a variable name so more things fit on one line.
5. Fix various comments.
llvm-svn: 32759
Fix this by ensuring that a bitcast is inserted to do sign switching. This
is only temporarily needed as the merging of signed and unsigned is next
on the SignlessTypes plate.
llvm-svn: 32757
This patch removes the SetCC instructions and replaces them with the ICmp
and FCmp instructions. The SetCondInst instruction has been removed and
been replaced with ICmpInst and FCmpInst.
llvm-svn: 32751
pass managers. Otherwise, stale available analysis info, from the managers not
yet run, may cause pass manager to take wrong turn.
This fixes CBE test failures reported by nightly tester.
