Reid Kleckner [Tue, 30 Jun 2015 22:46:59 +0000 (22:46 +0000)]
[SEH] Add new intrinsics for recovering and restoring parent frames

The incoming EBP value established by the runtime is actually a pointer
to the end of the EH registration object, and not the true parent
function frame pointer. Clang doesn't need llvm.x86.seh.exceptioninfo
anymore because we know that the exception info pointer is at a fixed
offset from this incoming EBP.

The llvm.x86.seh.recoverfp intrinsic takes an EBP value provided by the
EH runtime and returns a pointer that is usable with llvm.framerecover.

The llvm.x86.seh.restoreframe intrinsic is inserted by the 32-bit
specific preparation pass in blocks targetted by the EH runtime. It
re-establishes any physical registers used by the parent function to
address the stack, such as the frame, base, and stack pointers.

Neither of these intrinsics correctly handle stack realignment prologues
yet, but it's possible to add that later.

[DebugInfo] Let IRBuilder::SetInsertPoint(BB::iterator) update current debug location.

IRBuilder::SetInsertPoint(BB, BB::iterator) is an older version of

the current debug location of emitted instruction, while the former
doesn't, which is confusing.

Unify the behavior of these methods: now they both set current debug
location to the debug location of instruction at insertion point.

The callers of IRBuilder::SetInsertPoint(BB, BB::iterator) doesn't

location). On the contrary, sometimes they (e.g. SCEV) *should* be

Peter Collingbourne [Mon, 29 Jun 2015 22:04:09 +0000 (22:04 +0000)]
Teach LTOModule to emit linker flags for dllexported symbols, plus interface cleanup.

This change unifies how LTOModule and the backend obtain linker flags
for globals: via a new TargetLoweringObjectFile member function named
emitLinkerFlagsForGlobal. A new function LTOModule::getLinkerOpts() returns
the list of linker flags as a single concatenated string.

This change affects the C libLTO API: the function lto_module_get_*deplibs now
exposes an empty list, and lto_module_get_*linkeropts exposes a single element
which combines the contents of all observed flags. libLTO should never have
tried to parse the linker flags; it is the linker's job to do so. Because
linkers will need to be able to parse flags in regular object files, it
makes little sense for libLTO to have a redundant mechanism for doing so.

The new API is compatible with the old one. It is valid for a user to specify
multiple linker flags in a single pragma directive like this:

 #pragma comment(linker, "/defaultlib:foo /defaultlib:bar")

The previous implementation would not have exposed
either flag via lto_module_get_*deplibs (as the test in
TargetLoweringObjectFileCOFF::getDepLibFromLinkerOpt was case sensitive)
and would have exposed "/defaultlib:foo /defaultlib:bar" as a single flag via
lto_module_get_*linkeropts. This may have been a bug in the implementation,
but it does give us a chance to fix the interface.

ARM: add correct kill flags when combining stm instructions

When the store sequence being combined actually stores the base register, we
should not mark it as killed until the end.

7 years agoX86: Rework inline asm integer register specification.
Matthias Braun [Mon, 29 Jun 2015 21:35:51 +0000 (21:35 +0000)]
X86: Rework inline asm integer register specification.

This is a new version of http://reviews.llvm.org/D10260.

It turned out that when you specify an integer register in inline asm on
x86 you get the register of the required type size back. That means that
X86TargetLowering::getRegForInlineAsmConstraint() has to accept any of
the integer registers and adapt its size to the given target size which
may be any 8/16/32/64 bit sized type. Surprisingly that means given a
constraint of "{ax}" and a type of MVT::F32 we need to return X86::EAX.

This change makes this face explicit, the previous code seemed like
working by accident because there it never returned an error once a
register was found. On the other hand this rewrite allows to actually
return errors for invalid situations like requesting an integer register
for an i128 type.

format. There is no concept of a dynamic or a static symbol. Storing this
on the iterator also makes us do more work per symbol than necessary. To fetch
a name we would:

* Find if we had a static or a dynamic symbol.
