Alkis Evlogimenos eeea81483f Do a separate pass to compute spill weights because doing it inline 
with live intervals was missing registers that were used before they
were defined (in the arbitrary order live intervals numbers
instructions).

Chris Lattner 547508d542 Hrm is a really nasty ommission. The lack of this destructor was causing abstract 
types to never be deleted, manifesting itself as many OpaqueType objects being
leaked.  Whoops.

Chris Lattner 601415ed84 Do not delete the type holder until after the call instruction has been 
constructed!

John Criswell 80ce0e620e Modified the logic so that library objects with main() are only linked in 
if the program currently has main undefined.

Alkis Evlogimenos 7d7d7e89d4 Change the way free regusters are computed and perform better 
allocation in the presence of preallocated intervals.

John Criswell b6d3cb9449 Modified the linker so that it always links in an object from an archive 
that defines the symbol "main."  This is a hack that ensures that programs
that place their main function in a library and then link it in
(i.e. Apache 2.x) get their main function linked in.

There is probably a more correct way to do this, but this works for now.

anything; it just causes the bug to go dormant.

Alkis Evlogimenos 2665d9c6f9 Change weight into a float so that we can take into account the

John Criswell d8c7a7fbaa Fix PR#193. 
Modified ReadArchiveBuffer() so that it dynamically allocates the
std::string object used to hold the bytecode object file's name.  This is
necessary because it is passed by reference to the new Module that is
allocated to represent the bytecode object, and previously we were
using a std::string that disappeared on function exit.

 2003-12-20 17:28:15 +00:00
Alkis Evlogimenos 68cff6bf4d Remove floating point killer pass. This is now implemented in the 
instruction selector by adding a new pseudo-instruction
FP_REG_KILL. This instruction implicitly defines all x86 fp registers
and is a terminator so that passes which add machine code at the end
of basic blocks (like phi elimination) do not add instructions between
it and the branch or return instruction.
