Evan Cheng 0b77319742 Fix MachineCodeEmitter to use uintptr_t instead of intptr_t. This avoids some overflow issues. Patch by Thomas Jablin. 
llvm-svn: 60828
 2008-12-10 02:32:19 +00:00
Evan Cheng 9f3058f3be Rename isGVNonLazyPtr to isIndirectSym to reflect how it will be used.

 2008-11-10 01:08:07 +00:00
Evan Cheng b31a717527 Rename startFunctionStub to startGVStub since it's also used for GV non-lazy ptr. 
llvm-svn: 58897
 2008-11-08 08:02:53 +00:00
Evan Cheng 132de1983f Rename isGVLazyPtr to isGVNonLazyPtr relocation. This represents Mac OS X 
indirect gv reference. Please don't call it lazy.

Nicolas Geoffray 5457ce9ac3 Support for allocation of TLS variables in the JIT. Allocation of a global 
variable is moved to the execution engine. The JIT calls the TargetJITInfo
to allocate thread local storage. Currently, only linux/x86 knows how to
allocate thread local global variables.

Dale Johannesen 40f83ac649 When resolving a stub in x86-64 JIT, use a PC-relative branch 
rather than the absolute address if the target is within range.

Devang Patel 78e8a09f39 Mark function used by asm block as used, otherwise optimizer may not see the use and may delete the function.

Evan Cheng 68bd1546ab X86-64 PIC jump table values are different from x86-32 cases, they are dest - table base. 
llvm-svn: 53660
 2008-07-16 01:33:08 +00:00
Dan Gohman 76600aa35c Fixes for being compiled PIC on Linux. This isn't the most 
general solution possible, but it's a fairly simple one.
Based on a patch from the OpenGTL project!

Nicolas Geoffray a7557dfe71 Correlate stubs with functions in JIT: when emitting a stub, the JIT tells the memory manager which function 
the stub will resolve.

Anton Korobeynikov 1b1250770c Erm, really disable :) 
llvm-svn: 45319
 2007-12-22 20:46:24 +00:00
Anton Korobeynikov d34112a4ee Disable, until we'll really need it

Anton Korobeynikov 77eb5e649d Clarify the need of CFI() stuff 
llvm-svn: 44819
 2007-12-10 23:08:35 +00:00
Anton Korobeynikov a6b0f7e244 Provide convenient way to disable CFI stuff for old/broken assemblers. 
Use it for Darwin.

llvm-svn: 44818
 2007-12-10 23:04:38 +00:00
Chris Lattner 8a72a7d586 Disable cfi directives for now, darwin does't support them. 
These should probably be something like:

  CFI(".cfi_def_cfa_offset 16\n")

where CFI is defined to a noop on darwin and other platforms
that don't support those directives.

Anton Korobeynikov 657be86229 And finally annotate X86-64 version of callback. 
All bad stuff from SSE version is implicitely inherited :)

llvm-svn: 44794
 2007-12-10 15:27:07 +00:00
Anton Korobeynikov 88e9d082d8 Provide annotation for SSE version of callback. It's even more 
broken, because doesn't mark xmm regs properly

llvm-svn: 44793
 2007-12-10 15:13:55 +00:00
Anton Korobeynikov 81e9dc4af7 Annotate JIT callback function with call frame infromation. 
This will allow us (theoretically) to unwind through JITer.
The code wasn't verified, so I'm pretty sure offsets are wrong :)

Anton Korobeynikov b8d8b82950 Save all registers by default, as they can be used to pass parameters 
for "inreg" calls

llvm-svn: 33631
 2007-01-29 21:28:01 +00:00
Evan Cheng 62cdc3f011 - Fix X86-64 JIT by temporarily disabling code that treats GV address as 32-bit 
immediate in small code model. The JIT cannot ensure GV's are placed in the
lower 4G.
- Some preliminary support for large code model.

llvm-svn: 30990
 2006-10-16 22:53:28 +00:00
Evan Cheng afb610468b Added a X86CompilationCallback variant which saves XMM argument registers for targets with SSE.

Evan Cheng 78bf1074fc Resolve BB references with relocation. 
llvm-svn: 29351
 2006-07-27 18:21:10 +00:00
Evan Cheng f6acb34d23 - Refactor the code that resolve basic block references to a TargetJITInfo 
method.
- Added synchronizeICache() to TargetJITInfo. It is called after each block
  of code is emitted to flush the icache. This ensures correct execution
  on targets that have separate dcache and icache.
- Added PPC / Mac OS X specific code to do icache flushing.

Evan Cheng 28a95491d9 Let X86CompilationCallback pass previous frame and return address to X86CompilationCallback2. Remove alloca hack. 
llvm-svn: 28982
 2006-06-29 01:48:36 +00:00
Evan Cheng 38c5aee959 Simplify X86CompilationCallback: always align to 16-byte boundary; don't save EAX/EDX if unnecessary. 
llvm-svn: 28910
