Chris Lattner 1dfa97034d Allow for fixed objects to reside in the local area, and if they don't to not
clobber them by allocating other objects in the same space!

Alkis Evlogimenos 6a35516dcc Add back machine code deleter pass until we get a MachineCode pass
that will be responsible for the creation of MachineFunctions and will
be required by all MachineFunctionPass passes.

Alkis Evlogimenos fccb75d91e Modularize implementation of LeakDetector into a typed template
implementation class. This makes the code simpler and allows for more
types to be added easily. It also implements caching for generic
objects (it was only available for llvm objects).

Chris Lattner 7dceed5ff9 The prologue/epilogue related method calls have no reason to return a value,
make them return void.

This allows us to avoid some costly MBB.size() calls

Chris Lattner 0c48a03374 A target that doesn't support these intrinsics will still meet spec (the
intrinsic will always produce zero), but it will behave unexpectedly, so
warn like GCC does.

Alkis Evlogimenos 5a92240270 Use newly added next() and prior() utility functions.
llvm-svn: 11430
2004-02-14 01:18:34 +00:00
Alkis Evlogimenos 7c6e4d5ae6 Add next() and prior() iterator utility functions. Unlike std::advance
they do not modify the passed iterator but return a copy.

next(myIt) returns copy of myIt incremented once
next(myIt, n) returns copy of myIt incremented n times
prior(myIt) returns copy of myIt decremented once
prior(myIt, n) returns copy of myIt decremented n times

While at it remove obsolete implementation of mapped_iterator.

Chris Lattner 0591bb5bc8 Convert the C backend into a target, for use with LLC. This allows us to use
the lowerallocations pass to eliminate malloc/free warnings and hackish code

Chris Lattner 9fae109121 Change how we create the cwriter, and add a buttload of libraries that it now
needs.  This will be fixed shortly

Chris Lattner b09176a1e2 Change access to the cwriter
llvm-svn: 11406
2004-02-13 23:00:45 +00:00
Chris Lattner d2b6e183e9 Make the cwriter use the lowerinvoke pass so that it can either use "disabled exceptions" or
"expensive exceptions" controlled by an option.  Also refactor and eliminate a bunch of cruft.
This is a temporary solution and causes millions of warnings to pour out of programs that use
exceptions, but it should fix the problem with sparc and the 'write' declaration (PR190).
Subsequent changes will make this stink much less

llvm-svn: 11405
2004-02-13 23:00:29 +00:00
Chris Lattner 067b6bb9b2 New testcase. The CFE should not generate illegal LLVM intrinsics, even if
the input program is horribly broken (like 126.gcc).
