llvm-svn: 37405

Reid Spencer ff38cf8880 For PR1486: 
Avoid overwriting the APInt instance with 0 bytes which causes the bitwidth
to be set to 0 (illegal) producing a subsequent assert.

Reid Spencer 80fcb754d9 On Linux platforms and at optimization levels -O1 and above, llvm-gcc can 
turn "putchar" calls into _IO_putc calls which is a lower-level interface.
This patch allows these calls to be executed by lli in interpreter mode.

Reid Spencer 07ae5465cd Print integer values as both decimal and hexadecimal for convenience 
of verifying result values when debugging.

Reid Spencer 65ba7501fc Implement printing of instruction result values when debug info is turned 
on. This helps to speed up the debugging time by showing computational
results as the program executes.

Reid Spencer 0454316c79 Bitcast all the bits of a floating point value, not just one. The zero 
extension is needed because the constructor for the Destination value
causes the APInt to have a bit width of 1.
Patch by Guoling Han.

Reid Spencer 1d48207f5b 1. Don't swap byte order in scanf. It isn't necessary and leads to 
incorrect results (canonicalization was dropped several commits ago).
2. Add support for fscanf.
3. Suppress a warning about cast to pointer from non-pointer-sized integer.

Reid Spencer a68c374e7e We only need one putchar which gives it a shot at getting matched by its 
users.

 2007-04-17 17:38:28 +00:00
Reid Spencer c57be6cb4e Implement @sext and @zext parameter attribute handling properly instead of 
forcing every small argument of every function regardless of attributes or
calling convention to be expanded.

Reid Spencer 8c3d3dce2b For PR1293: 
* Rename the FunctionType* parameter from M to FT on all the functions.
* Implement a fix for PR1293 by just asserting that library functions that
  must return pointers should have pointer typed results. This just makes
  sure that we don't attempt to use an uninitialized integer or something
  later on.

Reid Spencer 4e42790c43 1. Make StoreValueToMemory a little more efficient by not requiring caller 
to make a copy of the GenericValue.
2. Fix a copy & paste bug in StoreValueToMemory where 64-bit values were
   truncated to 32

 2007-03-06 05:03:16 +00:00
Reid Spencer 1efc4aaf84 Fix some thinko's in the last patch. PtrSize has to be in bits and we 
might need to zext not just trunc the value.

llvm-svn: 34955
 2007-03-06 03:46:41 +00:00
Reid Spencer 10dbc1e896 Fix a bug in IntToPtr. Truncating to 64-bits only works if the integer 
is larger. Adjust so that it truncates to pointer width, only if necessary.

 2007-03-06 03:41:50 +00:00
Reid Spencer c764c55745 Simplify code as a result of the change in GenericValue to have a single 
integer field of type APInt instead of different sized integer fields.

llvm-svn: 34952
 2007-03-06 03:11:31 +00:00
Reid Spencer 40015aad5a Radically simplify execution. This patch gets rid of all the special 
handling for integer of various sizes. GenericValue now has just a single
integer field of type APInt. We use its facilities directly in the
execution of all instructions.

llvm-svn: 34951
 2007-03-06 03:09:31 +00:00
Reid Spencer c45e10474a Adjust and simplify external function processing now that GenericValue has 
a single integer field of type APInt.

llvm-svn: 34950
 2007-03-06 03:08:12 +00:00
Reid Spencer 7f68713eb8 APInt's are no longer allocated on the heap because they are direct 
members of GenericValue. Consequently the code to clean them up isn't
needed.

llvm-svn: 34948
 2007-03-06 03:06:48 +00:00
Reid Spencer 2d89fa84bc Remove the insufficient code in Interpreter::create that computed the 
Target DataLayout incorrectly. For now, we'll trust that the module has
got the correct DataLayout. In the future, this needs to be changed to
tell the TargetData to be "current host".

llvm-svn: 34947
 2007-03-06 03:05:57 +00:00
Reid Spencer 87aa65f40e Simplify things significantly because GenericValue now has a single integer 
field, of type APInt, instead of multiple integer fields. Also, get rid of
the special endianness code in StoreValueToMemory and LoadValueToMemory.
ExecutionEngine is always used to execute on the host platform so this is
now unnecessary.

llvm-svn: 34946

Reid Spencer ec8c51c1b1 Complete the APIntification of the interpreter. All asserts for > 64 bits 
have been removed and dealt with. The interpreter should now be able to
execute any LLVM program using any bit width.

 2007-03-03 08:38:04 +00:00
Reid Spencer 00919f5769 Avoid memory leakage by having caller construct the APInt for the 
destination value of LoadValueFromMemory.

llvm-svn: 34883
 2007-03-03 08:36:29 +00:00
Reid Spencer 54c6e84c83 Implement APInt support for the binary operators. 
Move the getConstantExpr function towards the end of the file so we don't
need a dozen forward declarations.

llvm-svn: 34877
 2007-03-03 06:22:22 +00:00
Reid Spencer 72aafa1d49 1. Have the ExecutionContext keep track of the APInt's allocated and 
ensure they are cleaned up when the stack frame exits.
2. Move a function to the Execution.cpp file where it belongs.

Chris Lattner 4da5e17cfc From Dan Gohman: 
While preparing http://llvm.org/PR1198 I noticed several asserts
protecting unprepared code from i128 types that weren't actually failing
when they should because they were written as assert("foo") instead of
something like assert(0 && "foo"). This patch fixes all the cases that a
quick grep found.

 2007-02-05 21:19:13 +00:00
Reid Spencer 2341c22ec7 Changes to support making the shift instructions be true BinaryOperators. 
This feature is needed in order to support shifts of more than 255 bits
on large integer types.  This changes the syntax for llvm assembly to
make shl, ashr and lshr instructions look like a binary operator:
   shl i32 %X, 1
instead of
   shl i32 %X, i8 1
Additionally, this should help a few passes perform additional optimizations.
