 - Add unbuffered flag to raw_ostream, forwarded by raw_fd_ostream and
   used by raw_stderr_ostream.

Also fixed a punctuation error in the header comment.
This fixes PR3775.

llvm-svn: 66542

to obtain debug info about them.
Introduce helpers to access debug info for global variables. Also introduce a
helper that works for both local and global variables.

If a function is marked alwaysinline, it must be inlined (possibly for correctness). Do so even if the callee has dynamic alloca and the caller doesn't.

if needed. This simplifies the code a little, and is needed for an
upcoming refactoring.

allocating memory in the JIT.  This is insanely inefficient, but
hey, most people implement their own memory managers anyway.

ARM target now also recognize triplets like thumbv6-apple-darwin and set thumb mode and arch subversion. Eventually thumb triplets will go way and replaced with function notes.

ARM isLegalAddressImmediate should check if type is a simple type now that optimizer can create values of funky scalar types.

Yet another case where the spiller marked two uses of the same register on the same instruction as kill. This fixes PR3706.

as not accessing memory.

is really really long dead.

llvm-svn: 66417

whether a global is dead or not.  This should fix PR3749 - linker adds 
spurious use to appending globals.  I can't reasonably add a testcase
for this, because the bc writer/reader strip dead constant users.

validate an invariant so that the asmparser rejects a bad construct
instead of the verifier.  Before:

llvm-as: assembly parsed, but does not verify as correct!
Invalid struct return type!
i64 (%struct.Type*, %struct.Type*)* @foo

after:

llvm-as: t.ll:5:8: functions with 'sret' argument must return void
define i64 @foo(%struct.Type* noalias nocapture sret %agg.result, %struct.Type* nocapture byval %t) nounwind {
       ^


Second, check that void is only used where allowed (in function return types) not in
arbitrary places, fixing PR3747 - Crash in llvm-as with void field in struct.  We
now reject that example with:

$ llvm-as t.ll
llvm-as: t.ll:1:12: struct element can not have void type
%x = type {void}
           ^

llvm-svn: 66394

by checking that the top-level type of a gep is sized. This
causes us to reject the example with:

llvm-as: t2.ll:2:16: invalid getelementptr indices
getelementptr i32()* null, i32 1
              ^
