Chris Lattner 0574e47dca Simplify some code
llvm-svn: 28066
2006-05-03 00:13:06 +00:00
Chris Lattner b8065a9a3a Several related changes:
1. Change several methods in the MachineCodeEmitter class to be pure virtual.
2. Suck emitConstantPool/initJumpTableInfo into startFunction, removing them
   from the MachineCodeEmitter interface, and reducing the amount of target-
   specific code.
3. Change the JITEmitter so that it allocates constantpools and jump tables
   *right* next to the functions that they belong to, instead of in a separate
   pool of memory.  This makes all memory for a function be contiguous, and
   means the JITEmitter only tracks one block of memory now.

2006-05-02 23:22:24 +00:00
Chris Lattner 23621fe8f4 Do not make the JIT memory manager manage the memory for globals. Instead
just have the JIT malloc them.

Chris Lattner 25b95ed868 Minor cleanups, no functionality change.
llvm-svn: 28061
2006-05-02 21:44:14 +00:00
Chris Lattner c9aa3715e8 Refactor the machine code emitter interface to pull the pointers for the current
code emission location into the base class, instead of being in the derived classes.

This change means that low-level methods like emitByte/emitWord now are no longer
virtual (yaay for speed), and we now have a framework to support growable code
segments.  This implements feature request #1 of PR469.

Nate Begeman 4ca2ea5b43 JumpTable support! What this represents is working asm and jit support for
x86 and ppc for 100% dense switch statements when relocations are non-PIC.
This support will be extended and enhanced in the coming days to support
PIC, and less dense forms of jump tables.

Jeff Cohen 2439669c6f The interpreter assumes that the caller of runFunction() must be lli, and
therefore the function being called must be a main() returning an int.  The
consequences when these assumptions are false are not good, so don't assume
them.

Jeff Cohen 69e849014c Teach the interpreter to handle global variables that are added to a module after

llvm-svn: 22554
2005-07-29 23:40:16 +00:00
Andrew Lenharth 3444cf5128 Like constants, globals on some platforms are GOT relative. This means they have to be allocated
near the GOT, which new doesn't do.  So break out the allocate into a new function.

Also move GOT index handling into JITResolver.  This lets it update the mapping when a Lazy
function is JITed.  It doesn't managed the table, just the mapping.  Note that this is
still non-ideal, as any function that takes a function address should also take a GOT
index, but that is a lot of changes.  The relocation resolve process updates any GOT entry
it sees is out of date.

Reid Spencer 79876f52aa For PR540:
This patch completes the changes for making lli thread-safe. Here's the list
of changes:
* The Support/ThreadSupport* files were removed and replaced with the
  MutexGuard.h file since all ThreadSupport* declared was a Mutex Guard.
  The implementation of MutexGuard.h is now based on sys::Mutex which hides
  its implementation and makes it unnecessary to have the -NoSupport.h and
  -PThreads.h versions of ThreadSupport.

* All places in ExecutionEngine that previously referred to "Mutex" now
  refer to sys::Mutex

* All places in ExecutionEngine that previously referred to "MutexLocker"
  now refer to MutexGuard (this is frivolous but I believe the technically
  correct name for such a class is "Guard" not a "Locker").

These changes passed all of llvm-test. All we need now are some test cases
that actually use multiple threads.

Chris Lattner 1edd79a1bc Now that we have ghost linkage, we can force resolution of external symbols
immediately instead of lazily.

In this program, for example:

int main() {
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
  printf("hello world\n");
}

We used to have to go through compilation callback 4 times (once for each
call to printf), now we don't go to it at all.

Thanks to Misha for noticing this, and for adding the initial ghost linkage
patches.
