Dan Gohman ec4e1b67bf Truncate from i64 to i32 is "free" on x86-32, because it involves

Douglas Gregor 678f90df09 Use CXXPseudoDestructorExpr as the stored representation for dependent
expressions that look like pseudo-destructors, e.g.,

  p->T::~T()

where p has dependent type.

At template instantiate time, we determine whether we actually have a
pseudo-destructor or a member access, and funnel down to the
appropriate routine in Sema.

Fixes PR6380.

Scott Michel 0ab0ad93bd Large stack frame patch for the CellSPU: handle stack frames that exceed 8176
(511*16) bytes register displacement (D-form).

NOTE: This is a potential headache, given the SPU's local core limitations,
allowing the software developer to commit stack overrun suicide unknowingly.
Also, large SPU stack frames will cause code size explosion. But, one presumes
that the software developer knows what they're doing...

Douglas Gregor 651fe5ec20 Retain complete source information for the type after the '~' in a
CXXPseudoDestructorExpr. 

Update template instantiation for pseudo-destructor expressions to use
this source information and to make use of
Sema::BuildPseudoDestructorExpr when the base expression is dependent
or refers to a scalar type.

Bill Wendling 88fdcd323d LLVM puts padding bytes in the __gcc_except_tab section after the
GCC_except_table label but before the Lexception, which the FDE references.
This causes problems as the FDE does not point to the start of an LSDA chunk.

Use an unnormalized uleb128 for the call-site table length that includes the
padding.

Jakob Stoklund Olesen 63af51c1c8 Create a stack frame on ARM when
- Function uses all scratch registers AND
- Function does not use any callee saved registers AND
- Stack size is too big to address with immediate offsets.

In this case a register must be scavenged to calculate the address of a stack
object, and the scavenger needs a spare register or emergency spill slot.

Dan Gohman 4b2b48daba Make getTypeSizeInBits work correctly for array types; it should return
the number of value bits, not the number of bits of allocation for in-memory
storage.

Make getTypeStoreSize and getTypeAllocSize work consistently for arrays and
vectors.

Fix several places in CodeGen which compute offsets into in-memory vectors
to use TargetData information.

This fixes PR1784.

Douglas Gregor 0d5b0a1e5e ActOnPseudoDestructorExpr now performs all semantic analysis for
pseudo-destructor expressions, and builds the CXXPseudoDestructorExpr
node directly. Currently, this only affects pseudo-destructor
expressions when they are parsed, but not after template
instantiation. That's coming next...

Improve parsing of pseudo-destructor-names. When parsing the
nested-name-specifier and we hit the sequence of tokens X :: ~, query
the actual module to determine whether X is a type-name (in which case
the X :: is part of the pseudo-destructor-name but not the
nested-name-specifier) or not (in which case the X :: is part of the
nested-name-specifier).
