Chris Lattner 68784efaf6 optimize builtin_isnan/isinf to not do an extraneous extension from 
float -> double (which happens because they are modelled as int(...)
functions), and add a testcase for isinf.

llvm-svn: 103167
 2010-05-06 05:50:07 +00:00
Chris Lattner 43660c5bc0 implement part of PR6083: codegen support for isinf. Like isnan, 
this is generating correct but suboptimal (extra extend to double)
code for the float case.  Will investigate next.

Chandler Carruth a77a72734c Remove a dependency on Frontend headers in the Driver library. Also saves 
building and passing arguments to cc1 layer when setting values to their
defaults.

Zhongxing Xu 1a56a488ed Turn -analyzer-inline-call on for C functions. This also fixed a bug that 
after inlining post-call checking shouldn't be done.

llvm-svn: 103161
 2010-05-06 03:38:27 +00:00
Zhongxing Xu 9174b2c2f9 Make -analyzer-inline-call not a separate analysis. Instead it's a boolean 
flag now, and can be used with other analyses. Only turned it on for C++ 
methods for now.

Dan Gohman d351116be0 Handle the case where open(2) or close(2) is interrupted by a signal when 
automatic syscall restarting is disabled.

Also, fix the build on systems which don't define EWOULDBLOCK.

 2010-05-06 01:54:03 +00:00
Evan Cheng 8f99a1c6b4 Adding pseudo 256-bit registers QQ0 . . . QQ7 to represent pairs of Q registers. These will be used to model VLD2 / VST2 instructions in order to get substantially better codegen for them.

Dan Gohman ef969f3539 Handle EWOULDBLOCK as EAGAIN. And add a comment explaining why 
EAGAIN and EWOULDBLOCK are used here.

Also, handle the case where a write call is interrupted after
some data has already been written.

Douglas Gregor e902956f59 Partial and full specializations of a class template may have a 
different tag kind ("struct" vs. "class") than the primary template,
which has an affect on access control.

Should fix the last remaining Boost.Accumulors failure.

Ted Kremenek 5b0773e201 Workaround a really serious caching bug in SourceManager::isBeforeInTranslationUnit() where the 
method will sometimes return different results for the same input SourceLocations.  I haven't
unraveled this method completely yet, so this truly is a workaround until a better fix comes
along.

Chandler Carruth f3983652eb Clean up the {} and else placement. This fixes an ambiguous else as well as 
picking a more consistent pattern.

Chris Lattner 35096e82c5 Fix PR7054 - Assertion `Symbol->isUndefined() && "Cannot define a symbol twice!"' failed. 
Users can write broken code that emits the same label twice with asm renaming,
detect this and emit a fatal backend error instead of aborting.

support a new bottom-up mode.

Chris Lattner 482fa218d4 fix rdar://7946934 - in some limited cases, the assembler should

Jim Grosbach 151cd8f159 Cleanup of ARMv7M support. Move hardware divide and Thumb2 extract/pack 
instructions to subtarget features and update tests to reflect.

Dan Gohman 50849c63e4 Emit debug info for MachineInstrs with unknown debug locations, instead 
of just letting them inherit the debug locations of adjacent instructions.

Debug info should aim to be either accurate or absent.

John McCall eebc832f43 Add IgnoreParenImpCasts() to Expr, which is basically like IgnoreParenCasts 
except it only skips implicit casts.

Also fix ObjCImplicitGetterSetterRefExpr's child_begin to skip the base expression
if it's actually a type reference (which you get with static property references).

Chris Lattner 3baada6fd7 Pass the globaldecl into GetOrCreateLLVMFunction so that llvm 
function attributes like byval get applied to the function 
definition. This fixes PR7058 and makes i386 llvm/clang bootstrap 
pass all the same tests as x86-64 bootstrap for me (the llvmc 
tests still fail in both).

Sean Callanan 4cd930f417 Fixed a sign-extension bug in the X86 disassembler 
that was causing PC-relative branch targets to be
evaluated incorrectly.  Also added support for
checking operand values to the llvm-mc tester.

Douglas Gregor bf1fb44efa When implicit definition of the copy-assignment operator fails, 
provide a note that shows where the copy-assignment operator was
needed. We used to have this, but I broke it during refactoring.

Douglas Gregor d450f06ef4 When we emit a non-constant initializer for a global variable of 
reference type, make sure that the initializer we build is the
of the appropriate type for the *reference*, not for the thing that it
refers to. Fixes PR7050.
