Justin Holewinski 47423e4fb9 PTX: Customize codegen passes in backend 
llvm-svn: 140306
 2011-09-22 16:45:37 +00:00
Justin Holewinski 28a548ebe3 PTX: Add new PTX-specific register allocator that keeps virtual registers 
instead of allocating physical registers.

This is part of a work-in-progress overhaul of the PTX register allocation scheme.

Garrison Venn 8cb0035ee9 Converted Exception demo over to using new 3.0 landingpad instruction. This 
was compiled and tested on OS X 10.7.1. It was not tested on LINUX. In 
addition the defined OLD_EXC_SYSTEM was not tested with this version.

Garrison Venn eb89d36b9d This is a hack to get the demo working with the new 3.0 exception 
infrastructure. As this makes the demo no longer a demo, and especially not a 
demo on how to use the llvm exception mechanism, this hack will shortly be 
changed to use the new 3.0 exception infrastructure. However for the time being 
this demo is an example on how to use the AutoUpgrade 
UpgradeExceptionHandling(...) function on < 3.0 exception handling code.

Benjamin Kramer cfd26cd744 The SSE version differences for fmin/fmax are more involved than I thought. 
- x87: no min or max.
- SSE1: min/max for single precision scalars and vectors.
- SSE2: min/max for single and double precision scalars and vectors.
- AVX: as SSE2, but also supports the wider ymm vectors. (this is covered by the isTypeLegal check)

Devang Patel 5e6b65cf0d Do not unnecessarily use AT_specification DIE because it does not add any value. 
Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

Bill Wendling f4bbc0416f The last verification check for the new EH model. 
This makes sure that the unwind destination of an invoke is a landing pad.

Benjamin Kramer 8a529dc10a llvm-objdump: Detach symbol listing from section enumeration for mach-o. 
This reduces memory usage as we don't add the same symbol multiple times anymore.

Bill Wendling 7b3fc8ee38 Attempt to update the shadow stack GC pass to the new EH model. 
This inserts a cleanup landingpad instruction and a resume to mimic the old
unwind instruction.

Benjamin Kramer e5e189f669 X86Disassembler: if verbose logging is going to nulls(), disable logging completely. 
Otherwise we'll spend a ridiculous amount of time pretty printing debug output and then discarding it.

Nadav Rotem bc9ba30158 [VECTOR-SELECT] Address one of the bugs in pr10902. 
Vector SetCC result types need to be type-legalized.
This code worked before because scalar result types are known to be legal.

assert(!"error message");

To:

  assert(0 && "error message");

which is more consistant across the code base.

Andrew Trick 924123acb3 Lower ARM adds/subs to add/sub after adding optional CPSR operand. 
This is still a hack until we can teach tblgen to generate the
optional CPSR operand rather than an implicit CPSR def. But the
strangeness is now limited to the selection DAG. ADD/SUB MI's no
longer have implicit CPSR defs, nor do we allow flag setting variants
of these opcodes in machine code. There are several corner cases to
consider, and getting one wrong would previously lead to nasty
miscompilation. It's not the first time I've debugged one, so this
time I added enough verification to ensure it won't happen again.

Eli Friedman 1815b688cc Make sure IPSCCP never marks a tracked call as overdefined in SCCPSolver::ResolvedUndefsIn. If we do, we can end up in a situation where a function is resolved to return a constant, but the caller is marked overdefined, which confuses the code later.
