Vikram S. Adve 2b630b4ec2 Rename 'dump-asm' to 'dump-input' and really print it just before code-gen.
llvm-svn: 7394
2003-07-29 19:58:00 +00:00
Vikram S. Adve dbc0eb6a2d Bug fix: don't unnecessarily pretty-print control-characters, some of
which were wrong (particularly, '\a' for '\007').

2003-07-29 19:57:34 +00:00
Vikram S. Adve 648ce40adf Add ConvertConstantToIntType() to unify all constant handling
that depends on machine register size.
Moved insertCallerSavingCode() to PhyRegAlloc and
moved isRegVolatile and modifiedByCall to TargetRegInfo: they are all
machine independent.  Remove several dead functions.

Vikram S. Adve 2353584afc Add code to support stack spill/temp offsets that don't fit in the
immed. field.  Moved insertCallerSavingCode() to PhyRegAlloc: it is
now machine independent.  Remove all uses of PhyRegAlloc.

Vikram S. Adve 9143f1962e All constant-evaluation code now unified into

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.

Fix problem with using branch operand reg. as temp. reg. when

John Criswell 4f37692a80 Enable JIT when the platform supports it.
Select /localhome/$USER when it exists.
Fix the checks for bidirectional and forward iterators so that they work with
version of GCC prior to 3.x.

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'

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 a845a566e1 * Disambiguate symbols before we start splitting module by functions
* Moved DisambiguateGlobalSymbols() out of the ReduceMisCodegenFunctions class
* Added an assert to have a cleaner exit if `main' is not found in the module

Misha Brukman 123c8576e5 Implemented cleanups as suggested by Chris:
* Use Module::getNamedFunction() to delete "main" instead of using a loop
* Compare function pointers instead of function names to determine equivalence
* Simplified creation of a 2-element vector containing zeroes
* Manually performed LICM on code
* Added an abort() in case a function we're considering occurs in something that
  is not an instruction
* Use DEBUG() around code sections instead of just in a statement in a loop,
  because GCC's DCE may not be good enough to completely remove it in a release
  build
* Print out a command that can be directly copied-and-pasted to re-execute
* Instead of just checking if a symbol begins with a dot and fixing it
  accordingly, use Mangler and fix all the problems (invalid chars in C symbol
  names) entirely
* The new `main' function has external linkage

Misha Brukman 3bb53319e8 The RTLD_GLOBAL flag allows symbols to be globally accessible, which makes
resolution of symbols in the .so possible (currently assists debugging with
bugpoint).

Misha Brukman 539f95933c BugDriver.h:
* Added method to query if BugDriver is executing the JIT currently.
  This provides the ability in adding code that is conditionally executed in
  codegen debugging phase.

CodeGeneratorBug.cpp:
* Delete test functions from the Safe module
* Code conditionally added when debugging the JIT:
  use the lazy resolver function added to Emitter.cpp to get function pointer
  by name. When compiled into an .so, this is the only way to get a pointer to
  an external function
* Added a symbol disambiguator which will keep symbols uniquely named across
  modules
* Delete generated files by default
* The function `main' *must* stay in the .bc file for the JIT, but that prevents
  debugging it alone. This patch makes the old `main' become `old_main' and adds
  a new function named `main' which just calls the original with the same
  parameters, thereby keeping functionality the same.

ExecutionDriver.cpp:
* Returned to getting unique filenames
* Simplified code choosing between using and not using shared library option

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.
