Devang Patel 1282b6e181 Avoid spliting loops where two split condition branches are not independent.

Chris Lattner 7a5e8e6502 improve iplist comments. Switch iplist from allocating its sentinal object (for 
end()) eagerly to allocating it lazily.  This saves a lot of memory for JIT applications
that read a module but don't materialize most of the functions (e.g. 62K for 252.eon).

Reid Spencer b813556f35 Regenerate. 
llvm-svn: 41138
 2007-08-17 05:45:26 +00:00
Reid Spencer 83bcd76596 Fix PR1606: 
The AC_CHECK_HEADER macro was used instead of AC_CHECK_HEADERS. The former does
not automatically add a #define to the configure variables while the latter
does. Consequently, the HAVE_PTHREAD_H symbol was not defined which caused the
Mutex.cpp file to compile to an empty implementation.

Evan Cheng 2c4ea1e411 New test. Make sure dynamic_stackalloc size is rounded up. 
llvm-svn: 41135
 2007-08-16 23:52:23 +00:00
Evan Cheng 1393d88cc6 Update test: dynamic_stackalloc size *must* be rounded to ensure stack ptr be left in a valid state. 
llvm-svn: 41134
 2007-08-16 23:51:28 +00:00
Evan Cheng 631ccc6144 If dynamic_stackalloc alignment is > stack alignment, first issue an instruction to align the stack ptr before the decrement. 
llvm-svn: 41133
 2007-08-16 23:50:06 +00:00
Evan Cheng 95667c532c - If a dynamic_stackalloc alignment requirement is <= stack alignment, then the alignment argument is ignored. 
- *Always* round up the size of the allocation to multiples of stack
alignment to ensure the stack ptr is never left in an invalid state after a dynamic_stackalloc.

Owen Anderson 5f208bea91 Cache non-local memory dependence analysis. This is a significant compile 
time performance win in most cases.

Chris Lattner 6b69568f85 This adds a bunch of static functions that implement unsigned 
two's complement bignum arithmetic.  They could be used to
implement much of APInt, but the idea is they are enough to
implement APFloat as well, which the current APInt interface
is not suited for.

Patch by Neil Booth!

Reid Spencer 19c21c593f Improve error handling in the linker by: 
1. Eliminate redundant error messages. LinkInFile and LinkInArchive
   already call the error() method in each case so there's no use
   telling the user again that an item couldn't be linked in.

2. Improve the formatting of error messages (separating content).

3. Change the wording for the warning about unrecognized files. Make
   it clear that the file is being ignored.

Evan Cheng 958cf3d43e If the source of a move is in spill slot, the reload may be folded to essentially a load from stack slot. It's ok to mark the stack slot value as available for reuse. But it should not be clobbered since the destination of the move is live.
