Chris Lattner 8706805dae This register is never used, disable it. 
llvm-svn: 7661
 2003-08-07 04:49:16 +00:00
Misha Brukman b611692487 Changing command-line option formats to be more consistent with LLVM style. 
llvm-svn: 7658
 2003-08-06 23:25:25 +00:00
Misha Brukman 8f18938d1c * Renamed option from `nopreselect' to `nopreopt' since it disables more than 
just PreSelection
* Wrapped code at 80 columns
* Added the DecomposeMultiDimRefs Pass to the JIT compilation path

llvm-svn: 7657
 2003-08-06 23:06:21 +00:00
Misha Brukman 79226d066e Use the registers g1 and g5 as temporaries for making far jumps and far calls, 
because saving i1 and i2 to their ``designated'' stack slots corrupts unknown
memory in other functions, standard libraries, and worse.

In addition, this has the benefit of improving JIT performance because we
eliminate writing out 4 instructions in CompilationCallback() and 2 loads and 2
stores.

llvm-svn: 7646
 2003-08-06 20:08:25 +00:00
Vikram S. Adve 792b48f4d1 1. Bug fix: was using SLL instead of SLLX for ULongTy. Chump. 
2. Handle fp-to-uint conversions directly here instead of relying on
   a pre-transformation to replace them with the 2-step conversion.
3. Use size rather than explicitly checking types when deciding what
   opcodes to use, wherever possible.  This is less error prone (the
   bug fix above was not the first time!).
4. Float-to-pointer casts shd now work though this hasn't been tested.

llvm-svn: 7645
 2003-08-06 18:48:40 +00:00
Vikram S. Adve 26125cbeb5 Remove conversion of fp-to-uint cast into a multi-step cast: 
this is not an optional transformation on SPARC and is now handled
directly by instruction selection.

Misha Brukman 4510698acb SparcV9CodeEmitter.cpp: 
* Doxygen-ified comments
* Added capability to make far calls (i.e., beyond 30 bits in CALL instr)
  which implies that we need to delete function references that were added by
  the call to addFunctionReference() because the actual call instruction is 10
  instructions away (thanks to 64-bit address construction)
* Cleaned up code that generates far jumps by using an array+loop

SparcV9CodeEmitter.h:
* Explained more of the side-effects of emitFarCall()

Vikram S. Adve 648ce40adf Add ConvertConstantToIntType() to unify all constant handling 
that depends on machine register size.

machine independent.  Remove several dead functions.

Vikram S. Adve c9cb319bcb 1. Bug fix: Don't use branch operand reg. as temp. reg. when 
spilling values used by an instruction in the delay slot of the branch
   (which will eventually be moved before the branch).
2. Bug fix:  Delete the delay slot instr, not the branch instr, when
   moving delay slot instr. out!!!!
3. Move code to insert caller-saves moved here from SparcRegInfo:
   it is now machine-independent.

Misha Brukman 0db560d8f6 * Correctly emit a far call if the target address does not fit into 30 bits 
instead of assert()ing
* Fixed a nasty bug where '07' was used instead of register 'o7'

llvm-svn: 7382
 2003-07-29 19:00:58 +00:00
Misha Brukman e47f069855 * Stop hard-coding a value for beginning of emitted code on Sparc since we can 
now handle far calls (i.e., beyond the 30-bit limit in call instructions).
* As a side-effect, this allows us to unify and clean up the mmap() call and
  code around it.

Misha Brukman 3bb53319e8 The RTLD_GLOBAL flag allows symbols to be globally accessible, which makes

Misha Brukman 057f460053 Add ability for external C code to get pointers to functions given their name. 
This us used by bugpoint -- when code is compiled to a shared object to be
JITted, it must use the JIT's lazy resolution method to find function addresses,
because some functions will not be available at .so load time, as they are in
the bytecode file.

llvm-svn: 7340
 2003-07-26 23:00:05 +00:00
Vikram S. Adve 536b19220c (1) Major fix to the way unused regs. are marked and found for the FP 
Single and FP double reg types (which share the same reg class).
    Now all methods marking/finding unused regs consider the regType
    within the reg class, and SparcFloatRegClass specializes this code.
(2) Remove machine-specific regalloc. methods that are no longer needed.
    In particular, arguments and return value from a call do not need
    machine-specific code for allocation.
(3) Rename TargetRegInfo::getRegType variants to avoid unintentional
    overloading when an include file is omitted.
