Chris Lattner 05fe6847a8 Implement SCCP/phitest.ll 
llvm-svn: 10763
 2004-01-12 03:57:30 +00:00
Chris Lattner 4d1bb94c3e New testcase, allow folding of binary operators that use PHI nodes, as long 
as the result of the binary operator is always constant.  This does not require
the PHI itself to be constant though.

Chris Lattner fafa2ff2d6 Implement Transforms/ScalarRepl/phinodepromote.ll, which is an important 
case that the C/C++ front-end generates.

Chris Lattner aacf2a5833 Implement: Assembler/2004-01-11-getelementptrfolding.llx 
llvm-svn: 10759
 2004-01-11 23:56:33 +00:00
Chris Lattner fcd7ccd425 This isn't really an assembler test. This tests to make sure the 
ConstantExpr::getGetElementPtr method folds two getelementptr instructions
when possible.

Chris Lattner 0180590bea Fix a regression that I introduced yesterday. :( 
llvm-svn: 10756
 2004-01-11 23:29:26 +00:00
Alkis Evlogimenos 52a714b45b Make LiveVariables::HandlePhysRegUse and 
LiveVariables::HandlePhysRegDef private they use information that is
not in memory when LiveVariables finishes the analysis.

Also update the TwoAddressInstructionPass to not use this interface.

Chris Lattner 65f901e23b Check in two changes: 
The first change (which is disabled) compactifies all of the function constant
pools into the global constant pool, in an attempt to reduce the amount of
duplication and overhead.  Unfortunately, as the comment indicates, this is
not yet a win, so it is disabled.

The second change sorts the typeid's so that those types that can be used
by instructions in the program appear earlier in the table than those that
cannot (such as structures and arrays).  This causes the instructions to
be able to use the dense encoding more often, saving about 5K on 254.gap.
This is only a .65% savings though, unfortunately. :(

Chris Lattner 3bcecb92f3 Update obsolete comments 
Fix iterator invalidation problems which was causing -mstrip to miss some
entries, and read free'd memory.  This shrinks the symbol table of 254.gap
from 333 to 284 bytes!  :)

llvm-svn: 10751
 2004-01-10 21:36:49 +00:00
Chris Lattner a2bfab849f Do not bother to emit a BytecodeBlock for an empty symbol table. This commonly 
occurs when the symbol table for a module has been stripped, making all of the
function local symbols go away.

This saves 6728 bytes in the stripped bytecode file of 254.gap (which obviously
has 841 functions), which isn't a ton, but helps and was easy.

Chris Lattner 3c01d683e3 An example testcase for use in the debugger. Currently you can do stuff like 
stepping, next'ing, finish'ing, stacktraces, source listings, etc.  You can't
print program variables yet though.

Oh, and I lost my nice commented version of funccall.ll  :(

Test with:
llvm-as funccall.ll
llvm-db funccall.bc
<arguments>

This is not automatically testable yet, and the C front-end doesn't support
debug information yet.  That said, it's a start.

Chris Lattner 1811fca71c First version of this document. It is still missing some pretty big pieces, and

This changes facilitaties the following:
1) It should be easier to incorporate new autoconf macros.
2) It allows for conversion to Automake (should we ever desire it).

physical). In register allocation, if this hint exists and we can map
it to a physical register (it is either a physical register or it is a
virtual register that already got assigned to a physical one) we use
that register if it is available instead of a random one in the free
pool.

it and the branch or return instruction.

Alkis Evlogimenos e5e2bd6777 Modify linear scan register allocator to use the two-address 
instruction pass. This also fixes all remaining bugs for this new
allocator to pass all tests under test/Programs.

Alkis Evlogimenos c17d57bd82 Modify local register allocator to use the two-address instruction pass. 
llvm-svn: 10513
 2003-12-18 13:08:52 +00:00
Alkis Evlogimenos 725021cb6c Add TwoAddressInstructionPass to handle instructions that have two or 
more operands and the two first operands are constrained to be the
same. The pass takes an instruction of the form:

        a = b op c

and transforms it into:

        a = b
        a = a op c

and also preserves live variables.

 2003-12-18 13:06:04 +00:00
Alkis Evlogimenos 4d87219486 Rename LiveIntervals::expired() to LiveIntervals::expiredAt(). 
llvm-svn: 10511
 2003-12-18 08:56:11 +00:00
Alkis Evlogimenos 15b8036b29 When a variable is killed and redifined in a basic block only one 
killing instruction is tracked. This causes the LiveIntervals to
create bogus intervals. The workaound is to add a range to the
interval from the redefinition to the end of the basic block.

llvm-svn: 10510
 2003-12-18 08:53:43 +00:00
Alkis Evlogimenos 40874c708f Handle multiple virtual register definitions gracefully. 
Move some of the longer LiveIntervals::Interval method out of the
header and add debug information to them. Fix bug and simplify range
merging code.

Chris Lattner 9e2b42a0c8 When we delete instructions from the loop, make sure to remove them from the 
AliasSetTracker as well.

llvm-svn: 10507
 2003-12-18 08:12:32 +00:00
Chris Lattner 44fea5416d Add a new AliassetTracker::remove method. Because we need to be able to remove 
a pointer from an AliasSet, maintain the pointer values on a doubly linked
list instead of a singly linked list, to permit efficient removal from the
middle of the list.

llvm-svn: 10501
 2003-12-17 22:06:08 +00:00
Misha Brukman b01a80aa94 Reorganized the Sparc backend to be more modular -- each different 
implementation of a Target{RegInfo, InstrInfo, Machine, etc} now has a separate
header and a separate implementation file.

This means that instead of a massive SparcInternals.h that forces a
recompilation of the whole target whenever a minor detail is changed, you should
only recompile a few files.

Note that SparcInternals.h is still around; its contents should be minimized.

llvm-svn: 10500
 2003-12-17 22:04:00 +00:00
Misha Brukman 423ad188da Since we are now in the 'llvm' namespace, the mangled C++ name of structs 
and hence the links, all change.
