Jakob Stoklund Olesen 25a404eb81 Include a source location when complaining about bad inline assembly.
Add a MI->emitError() method that the backend can use to report errors
related to inline assembly. Call it from X86FloatingPoint.cpp when the
constraints are wrong.

This enables proper clang diagnostics from the backend:

$ clang -c pr30848.c
pr30848.c:5:12: error: Inline asm output regs must be last on the x87 stack
  __asm__ ("" : "=u" (d));  /* { dg-error "output regs" } */

Jakob Stoklund Olesen 30a8563a61 Use a new strategy for preventing eviction loops in RAGreedy.
Every live range is assigned a cascade number the first time it is
involved in an eviction. As the evictor, it gets a new cascade number.
Every evictee is assigned the same cascade number as the evictor.

Eviction is prohibited if the evictor has a lower assigned cascade
number than the evictee.

This means that assigned cascade numbers are monotonically increasing
with every eviction, yet they are bounded by NextCascade which can only
be incremented by new live ranges. Thus, infinite loops cannot happen,
but eviction cascades can still be triggered by new live ranges as we
want.

Thanks to Andy for explaining this to me.

Johnny Chen 73a44f6b99 Furnish some docstrings to be swigified into the generated lldb.py module.
Especially SBProcess.ReadMemory() and SBProcess.WriteMemory() because the generated autodoc strings

Eli Friedman ad811f01d5 Make clang behave in a gcc-compatible way in the presence of multiple flags for the same x86 target feature (e.g. -mno-sse -msse). gcc uses a somewhat unintuitive algorithm here in that the enabled SSE instructions is based on the order of the *last* flag for *each* feature-level, so that "-mno-sse -msse2" only enables SSE2, but "-mno-sse -msse2 -msse" enables all SSE levels.
Issue reported on cfe-dev.

llvm-svn: 134294
2011-07-02 00:27:11 +00:00
Enrico Granata 0a3958e046 several improvements to "type summary":
- type names can now be regular expressions (exact matching is done first, and is faster)
 - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them
 - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays)
 - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier
 - basic support for ObjectiveC:
  - ObjectiveC inheritance chains are now walked through
  - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object
 - some bug fixes

Chandler Carruth edc2c64630 Move the Sema argument to all of the Sema-using helper functions in
SemaDeclAttr to the first argument. This makes them follow the very

Chandler Carruth ff4c4f0f8a Mechanical rename of 'd' Decl pointer parameters to 'D'. This is more
conventional in the rest of Clang's codebase, and closer to the current
style recommendations. It also makes the code more internally consistent
as FD, VD, etc are used frequently for particular decl variables.

Argyrios Kyrtzidis 7192a3b841 [ARC] When casting from a pointer to an objective-c object with known ownership, if the
cast type has no ownership specified, implicitly "transfer" the ownership of the cast'ed type

(NSString**)&x; // Casting as (__strong NSString**).

Argyrios Kyrtzidis d8701b60f7 -Remove Sema::ActOnCastOfParenListExpr and move most of its functionality to

-Make Sema::ActOnCastExpr handle a vector initializer both when the cast'ed expression
 is a ParenListExpr and when it is a ParenExpr.
-Ultimately make Sema::ActOnParenOrParenListExpr independent of what the cast type was.

Argyrios Kyrtzidis 7451d1cd00 [ARC] When casting from a pointer to an objective-c object with known ownership, if the

id x;
static_cast<NSString**>(&x); // Casting as (__strong NSString**).

Dan Gohman a293f24a0d Teach IVUsers to stop at non-affine expressions unless they are both
outside the loop and reducible.

This more completely hides them from LSR, which isn't usually able to
do anything meaningful with non-affine expressions anyway, and this
consequently hides them from SCEVExpander, which is acutely unprepared
for non-affine expressions.

Replace test/CodeGen/X86/lsr-nonaffine.ll with a new test that tests
the new behavior.

This works around the bug in PR10117 / rdar://problem/9633149, and is
generally an improvement besides.
