Daniel Dunbar 31b44e8f6c Normalize Subtarget constructors to take a target triple string instead of 
Module*.

Also, dropped uses of TargetMachine where unnecessary. The only target which
still takes a TargetMachine& is Mips, I would appreciate it if someone would
normalize this to match other targets.

Evan Cheng 02a765280f GV with ghost linkage (module being lazily streamed in in JIT lazy compilation mode) do not require extra load from stub. This fixes ExecutionEngine/2005-12-02-TailCallBug.ll.

Chris Lattner bd3e560f1a some minor simplifications. 
llvm-svn: 75274
 2009-07-10 20:53:38 +00:00
Chris Lattner e2f524f176 add a couple of predicates to test for "stub style pic in PIC mode" and "stub style pic in dynamic-no-pic" mode.

Chris Lattner 20073edf67 simplify fast isel by using ClassifyGlobalReference. This 
elimiantes the last use of GVRequiresExtraLoad, so delete it.

Chris Lattner 93f0f79178 eliminate GVRequiresRegister, replacing it with predicates we 
need for other purposes.

llvm-svn: 75243
 2009-07-10 07:38:24 +00:00
Chris Lattner dc842c06c2 move some classification logic around. Now GVRequiresExtraLoad 
is just a trivial wrapper around "ClassifyGlobalReference", which
stole a ton of logic from LowerGlobalAddress.

llvm-svn: 75237
 2009-07-10 07:20:05 +00:00
Chris Lattner b9af63a4d2 GVRequiresExtraLoad is now never used for calls, simplify it based on this. 
llvm-svn: 75232
 2009-07-10 05:52:02 +00:00
Chris Lattner ace6ec26d9 actually, just eliminate PCRelGVRequiresExtraLoad. It makes the code 
more complex and slow than just directly testing what we care about.

llvm-svn: 75231
 2009-07-10 05:48:03 +00:00
Chris Lattner 7277a807f0 There is only one case where GVRequiresExtraLoad returns true for calls: 
split its handling out to PCRelGVRequiresExtraLoad, and simplify code
based on this.

llvm-svn: 75230
 2009-07-10 05:45:15 +00:00
Chris Lattner 1cc7ae7c3b the "isDirectCall" operand of GVRequiresRegister is always false, eliminate it. 
llvm-svn: 75229
 2009-07-10 05:37:11 +00:00
Chris Lattner fef11d6e77 simplify some code based on the fact that picstyles != none are only valid 
in pic or dynamic-no-pic mode. Also, x86-64 never used picstylegot.

Anton Korobeynikov 77d1943637 The attached patches implement most of the ARM AAPCS-VFP hard float 
ABI. The missing piece is support for putting "homogeneous aggregates"
into registers.

Stefanus Du Toit 96180b5387 Update CPU capabilities for AMD machines 
- added processors k8-sse3, opteron-sse3, athlon64-sse3, amdfam10, and
barcelona with appropriate sse3/4a levels
- added FeatureSSE4A for amdfam10 processors
in X86Subtarget:
- added hasSSE4A
- updated AutoDetectSubtargetFeatures to detect SSE4A
- updated GetCurrentX86CPU to detect family 15 with sse3 as k8-sse3 and
family 10h as amdfam10

New processor names match those used by gcc.

Duncan Sands 12da8ce3d2 Introduce new linkage types linkonce_odr, weak_odr, common_odr 
and extern_weak_odr.  These are the same as the non-odr versions,
except that they indicate that the global will only be overridden
by an *equivalent* global.  In C, a function with weak linkage can
be overridden by a function which behaves completely differently.
This means that IP passes have to skip weak functions, since any
deductions made from the function definition might be wrong, since
the definition could be replaced by something completely different
at link time.   This is not allowed in C++, thanks to the ODR
(One-Definition-Rule): if a function is replaced by another at
link-time, then the new function must be the same as the original
function.  If a language knows that a function or other global can
only be overridden by an equivalent global, it can give it the
weak_odr linkage type, and the optimizers will understand that it
is alright to make deductions based on the function body.  The
code generators on the other hand map weak and weak_odr linkage
to the same thing.

Dan Gohman 561d1226b6 Tevert part of the x86 subtarget logic changes: when -march=x86-64 
is given, override the subtarget settings and enable 64-bit support.
This restores the earlier behavior, and fixes regressions on
Non-64-bit-capable x86-32 hosts.

This isn't necessarily the best approach, but the most obvious
alternative is to require -mcpu=x86-64 or -mattr=+64bit to be used
with -march=x86-64 when the host doesn't have 64-bit support. This
makes things little more consistent, but it's less convenient, and
it has the practical drawback of requiring lots of test changes, so
I opted for the above approach for now.

llvm-svn: 63642
 2009-02-03 18:53:21 +00:00
Dan Gohman 7403751e16 Change Feature64Bit to not imply FeatureSSE2. All x86-64 hardware has 
SSE2, however it's possible to disable SSE2, and the subtarget support
code thinks that if 64-bit implies SSE2 and SSE2 is disabled then
64-bit should also be disabled. Instead, just mark all the 64-bit
subtargets as explicitly supporting SSE2.

Also, move the code that makes -march=x86-64 enable 64-bit support by
default to only apply when there is no explicit subtarget. If you
need to specify a subtarget and you want 64-bit code, you'll need to
select a subtarget that supports 64-bit code.

Torok Edwin e83866065b Only force SSE level if it is not correct. 
Add an assert to check HasX86_64 status.

Torok Edwin a2d1f35e9a Implement -mno-sse: if SSE is disabled on x86-64, don't store XMM on stack for 
var-args, and don't allow FP return values

llvm-svn: 63495
 2009-02-01 18:15:56 +00:00
Torok Edwin 692ed0f67d should have removed the + when manually applying a patch! 
llvm-svn: 62973
 2009-01-25 20:29:34 +00:00
Torok Edwin 97be2f5840 revert this patch for now, because Codegen does still want to generate SSE code, 
for example in the case of va-args. XFAIL associated tests.

llvm-svn: 62972
 2009-01-25 20:21:24 +00:00
Torok Edwin a23c73bbdc If user explicitly asks not to use SSE, don't force it. This fixes LLVM part of PR3402.

Dale Johannesen 9efd2ce55b Make LoopStrengthReduce smarter about hoisting things out of 
loops when they can be subsumed into addressing modes.

Change X86 addressing mode check to realize that
some PIC references need an extra register.
(I believe this is correct for Linux, if not, I'm sure
someone will tell me.)

Evan Cheng 2a03c7e977 Re-did 60519. It turns out Darwin's handling of hidden visibility symbols are a bit more complicate than I expected. Both declarations and weak definitions still need a stub indirection. However, the stubs are in data section and they contain the addresses of the actual symbols.
