Reid Spencer 6967cd54f3 Fix for bug 391. 
Improve exeception handling around bcreader invocations.

llvm-svn: 14674
 2004-07-07 21:01:38 +00:00
Reid Spencer eb04d9bcb4 Add #include <iostream> since Value.h does not #include it any more.

Chris Lattner 8232621124 This code is a real mess, but at least get the JIT *building* on platforms 
(such as plan 9) without mmap.  Of course it won't RUN... but that's another
step.  :)

Brian Gaeke 1eec234f91 My fix for PR274 broke the build on Darwin/PPC. As I'm fairly certain this 
bug only affects Linux systems that use GLIBC, I'm going to put ifdefs around
the array.

Brian Gaeke 96e450b3b2 Address PR274 - '[JIT] Programs cannot resolve the fstat function' 
by trying to get the compiler to generate an undefined reference for it
and related functions which live in libc_nonshared.a on Linux.

Chris Lattner 9bcae072d1 Cleanup the JIT as per PR176. This renames the VM class to JIT, and merges the 
VM.cpp and JIT.cpp files into JIT.cpp.  This also splits some nasty code out

Misha Brukman 873cf93b6e Go back to allocating memory for each constant separately. Since SPARCs do not 
allow unaligned loads, that is probably the problem I've been seeing in numerous
SPARC test cases failing. X86, on the other hand, just slows down unaligned
accesses, since it must make 2 aligned accesses for each unaligned one.

Brian Gaeke a7669038fc Make CreateArgv part of lli rather than part of ExecutionEngine. 
Switch Interpreter and JIT's "run" methods to take a Function and a vector of
 GenericValues.
Move (almost all of) the stuff that constructs a canonical call to main()
 into lli (new methods "callAsMain", "makeStringVector").
Nuke getCurrentExecutablePath(), enableTracing(), getCurrentFunction(),
 isStopped(), and many dead decls from interpreter.
Add linux strdup() support to interpreter.
Make interpreter's atexit handler runner and JIT's runAtExitHandlers() look
 more alike, in preparation for refactoring.
atexit() is spelled "atexit", not "at_exit".

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.

Misha Brukman 7dee443c1c * If compiling on X86 or Sparc, automagically enable the JIT for that arch 
* Setting ENABLE_X86_JIT or ENABLE_SPARC_JIT on the `make' command-line will
  force the inclusion of that JIT on a different architecture
* If neither JIT is enabled (e.g., compiling on a different architecture), the
  -march option will not be available to LLI.
* As a side effect of the $ARCH variable, the Sparc LLI can now link just a bit
  faster by not including the x86 library.

Misha Brukman 0ccdecbdaa ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: HACK ALERT ::: 
The JIT is designed to code-generate a function at-a-time. That means that any
pass can only make local changes to its function. Period.

Because the Sparc PreSelection pass claims to be a BasicBlock pass while adding
globals to the Module, it cannot be run with the other passes, because by this
time, the globals have been output already by the JIT, and the addresses of any
globals appearing AFTER this point are not recognized.

However, the PreSelection pass is a requirement for correctness in the Sparc
codegen path, so it MUST be run.

Misha Brukman 56d27325c0 Allow for specification of which JIT to run on the commandline. 
`lli -march=x86' or `lli -march=sparc' will forcefully select the JIT even on a
different platform. Running lli without the -march option will select the JIT
for the platform that it's currently running on.

Pro: can test Sparc JIT (debug printing mode) on X86 -- faster to compile/link
LLVM source base to test changes.
Con: Linking lli on x86 now pulls in all the Sparc libs -> longer link time
(but X86 can bear it, right?)

In the future, perhaps this should be a ./configure option to enable/disable
target JITting...
