 2003-07-22 21:00:24 +00:00
John Criswell
ba5a656e6c Fixed the enable/disable options. The AC_ARG_ENABLE macro does not perform 
the *action-if-not-given* code when the --disable option is used.
Rather, the AC_ARG_ENABLE macro sets the $enableval variable, which then needs
to be checked to determine if --enable, --disable, or neither was specified.

582cf5be31 Initialize the target architecture based on compiler defines, so if compiled on 
x86 or Sparc, LLC will automatically default to that platform, no guessing
required. On another platform, it will default to `noarch' and will have to
guess which architecture to compile to.

bf46d75365 Please, save your applause^H^H^H^H^H^H^H^Hflames for the end... 
Avoid a fall-through in the (stubby) treatment of the longjmp intrinsic
call which causes llc & lli to core-dump.

Add a sort-of treatment of cast double to ulong. I am not really sure
what a user should expect to see upon casting a negative FP value to
unsigned long long. But with what is given here, I was able to write
a program that could cast -123.456 to ulong and back and get -123.0,
which seems like a step in the right direction.  GCC seems to give you
0. I don't know if I'd consider that useful.

These cases were coming up in GNU coreutils-5.0.

755aa86ca3 Cleaned up the code which chooses the appropriate value for the file descriptor 
to pass to dlsym() -- Linux/x86 wants 0 while Sparc/Solaris wants RTLD_SELF,
which is not zero. Thanks to Chris for the suggestion.

dbaf5f719c Dinakar and I fixed a bug where we were trying to get the initializer of 
an external constant.  Since external constants don't have initializers, we
were failing on an assert() call in llvm/GlobalVariable.h.

2d617afa1a (1) Added DSGraph::cloneReachableSubgraph and DSGraph::cloneReachableNodes 
to clone the subgraph reachable from a set of root nodes, into the
    current graph, merging the global nodes into those in the current graph.
(2) Added DSGraph::updateFromGlobalGraph() to rematerialize nodes from the
    globals graph into the current graph in both BU and TD passes.
(3) Added hash_set<const GlobalValue*> InlinedGlobals: a set of globals to
    track which globals have been inlined into the current graph from
    callers or callees.  In the TD pass, such globals are up-to-date and
    do not need to be rematerialized from the GlobalsGraph.
(4) Added StripIncompleteBit/KeepIncompleteBit to remove incomplete bit
    when cloning nodes into the globals graph.

96abba3e01 Rematerialize nodes from the globals graph into the current graph 
after all callees are inlined into the current graph.

NOTE: There's also a major bug fix for the BU pass in DataStructure.cpp,
which ensures that resolvable indirect calls are not moved out to the
globals graph, so that they are eventually inlined (if possible).
