Brian Gaeke 960707c335 Put all LLVM code into the llvm namespace, as per bug 109. 
llvm-svn: 9903
 2003-11-11 22:41:34 +00:00
Brian Gaeke 9ef636c698 Implement vaarg instruction. This is not quite perfect: 2003-08-11-VaListArg 
still causes a crash. But it's better than before.

llvm-svn: 9794
 2003-11-07 21:20:47 +00:00
Brian Gaeke 85baf8c65a popStackAndReturnValueToCaller() must advance instruction pointer to normal 
destination, if returning from an invoke.

Implement 'unwind' instruction.

llvm-svn: 9792
 2003-11-07 20:44:58 +00:00
Brian Gaeke 6d145eb65f Add stub version of unwind support 
llvm-svn: 9789
 2003-11-07 20:07:06 +00:00
Brian Gaeke a6454d3532 visitCallInst --> visitCallSite. 
Use visitCallSite to implement both CallInsts and InvokeInsts.

llvm-svn: 9788
 2003-11-07 20:04:22 +00:00
Brian Gaeke a6d48e4db2 Make the operation of visitCallInst() only depend on the CallSite. 
llvm-svn: 9787
 2003-11-07 19:59:08 +00:00
Brian Gaeke 18b59578c9 Use CallSites for call sites, instead of CallInsts. A revolutionary concept. 
llvm-svn: 9784
 2003-11-07 19:26:23 +00:00
Brian Gaeke 65cac90a92 Refactor the return-from-function code into popStackAndReturnValueToCaller(). 
Make external function calls slightly less special; now they get a stack frame.

llvm-svn: 9765
 2003-11-07 05:22:49 +00:00
Chris Lattner b5b9ba6ff6 Be friendly to gcc 3.4... good compiler. Nice compiler. 
llvm-svn: 9726
 2003-11-05 06:20:27 +00:00

llvm-svn: 9713
 2003-11-05 01:02:14 +00:00

llvm-svn: 9712
 2003-11-05 00:59:28 +00:00
Brian Gaeke e278c22380 Reduce the number of #includes. 
CurFrame, TraceMode, and the CachedWriter are history.
ArrayChecksEnabled and non-QuietMode are history.
The ExecutionAnnotations (SlotNumber, InstNumber, and FunctionInfo) are history.
ExecutionContext now keeps Values for each stack frame in a std::map.
Stop pre-initializing Values on the stack to 42.
Remove some dead variables, excess whitespace and commented-out code.
executeInstruction() is now part of run().
printValue() and print() are history.

 2003-10-24 19:59:01 +00:00

w/ interactive keyboard entry of names.
With that, Support.cpp is history.

llvm-svn: 8360
 2003-09-05 05:04:32 +00:00

Mung some comments.
Get rid of interpreter's PROFILE_STRUCTURE_FIELDS and PerformExitStuff
 which have been disabled forever.
Get rid of -abort-on-exception (make it always on).

llvm-svn: 4605
 2002-11-07 19:29:31 +00:00
Chris Lattner 61596ad266 Fix two problems: 
* Load Implementation can cause unaligned memory accesses, which caused
    problems for sparc.
  * cast from pointer to pointer would zero the upper 32 bits of the pointer
    which obviously causes problems on 64 bit hosts.
