Chris Lattner 1319429f4d Remove explicit support for tracing code. It should be linked into the
executable just like everything else.

Chris Lattner 13e8979767 Remove tracing code hack

2002-05-20 21:16:46 +00:00
Chris Lattner f7b31cceec Tracelib is now an LLVM library just like all other libraries in this
directory.

If the test code needs to be resurrected in the future, it should be moved
into the test/Programs directory, linking with tracelib.

Vikram S. Adve cf3c90d4c8 Add libsparc.a a second time to resolve link errors.
llvm-svn: 2661
2002-05-19 16:01:03 +00:00
Vikram S. Adve b810407ddb Link with test/Libraries/libinstr32.a for runtime routines
supporting tracing.  That should be moved to a "runtime" directory.

llvm-svn: 2660
2002-05-19 16:00:28 +00:00
Vikram S. Adve a77150b977 Added external functions for hashing pointers to sequence numbers.

2002-05-19 15:59:25 +00:00
Vikram S. Adve be31fcf252 Runtime routines to support tracing.
Currently includes code to hash pointers to sequence numbers.
The hash table should be separated out into a separate file
since that is generic.  The rest of this code is pretty small.

llvm-svn: 2655
2002-05-19 15:49:58 +00:00
Vikram S. Adve 423960a8a9 Fix libs and includes for compiling with llc.
llvm-svn: 2654
2002-05-19 15:47:52 +00:00
Vikram S. Adve e363307e49 Added log2 for log-base-2 and also modified IsPower2 to use it.
llvm-svn: 2653
2002-05-19 15:46:52 +00:00
Vikram S. Adve 18d5a88024 Added parameter IntRegSize for standard general-purpose register size.

2002-05-19 15:44:07 +00:00
Vikram S. Adve c479fd5cd9 New function CreateSignExtensionInstructions.
Methods now take MachineCodeForInstruction& as an argument and record
temporary values in it directly, instead of return the temps.
Really simplifies callers.

llvm-svn: 2651
2002-05-19 15:43:31 +00:00
Vikram S. Adve 58d578957d Many functions that returned a single MachineInstr now take a
vector of MachineInstr* to return multiple ones.

llvm-svn: 2650
2002-05-19 15:42:21 +00:00
Vikram S. Adve 5d78db2afb InstrnsBefore and InstrnsAfter are now vectors instead of deques.
May be slightly less efficient but significantly reduces special
cases interfaces in code generation.

2002-05-19 15:41:33 +00:00
Vikram S. Adve d379fe042a Better interface to generating machine instr for common cases
(many places still need to be updated to use this interface).

llvm-svn: 2648

Vikram S. Adve 47f37c3404 Hash pointer values to a sequence number to get identical results from
lli and llc.  This is controlled with options -tracehash on|off.

Also, added an option to specify which functions should be traced.
Particularly useful to reduce output volume in basic-block tracing.

Vikram S. Adve 16384011d2 Better folding getelementptr operations with mixed

when replacing constant values with immediates.

Vikram S. Adve 069d51612f cpValue2Value now needs a vector of MachineInstr to store return values.

Vikram S. Adve 1e45411a31 Annotation class for MachineInstr.
llvm-svn: 2643
2002-05-19 15:30:21 +00:00
Vikram S. Adve 2780d2dacb Numerous bug fixes:
-- passing FP arguments to functions with more than 6 arguments
-- passing FP arguments to varargs functions
-- passing FP arguments to functions with no prototypes
-- incorrect coloring for CC registers (both int and FP): interferences
   were being completely ignored for int CC and were considered but no
   spills were marked for fp CC!

Also some code improvements:
-- better interface to generating machine instr for common cases
   (many places still need to be updated to use this interface)
-- annotations on MachineInstr to communicate information from
   one codegen phase to another (now used to pass information about
   CALL/JMPLCALL operands from selection to register allocation)
-- all sizes and offests in class TargetData are uint64_t instead of uint

-- passing FP arguments to functions with no prototypes
-- incorrect stack frame size when padding a section

Chris Lattner 5b3057bb82 Fix bug: test/Regression/CBackend/2002-05-16-NameCollide.ll by tracking

Chris Lattner 053c0939e3 Fix bug: test/Regression/Transforms/InstCombine/2002-05-14-TouchDeletedInst.ll
"This testcase caused instcombine to fail because it got the same instruction on
it's worklist more than once (which is ok), but then deleted the instruction.
Since the inst stayed on the worklist, as soon as it came back up to be
processed, bad things happened, and opt asserted."

Chris Lattner a3c3456e7f Fix a major source of "type unsafety", where a cast is neccesary, but can
be put either before or after a load.  We chose to cast the value loaded
instead of the pointer to load from.
