Fangrui Song 789a46f2d7 [CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition 
Summary:
Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults
to -fsemantic-interposition).
Users need to specify -fsemantic-interposition to get semantic
interposition behavior.

Semantic interposition is currently a best-effort feature. There may
still be some cases where it is not handled well.

Tim Northover a009a60a91 IR: print value numbers for unnamed function arguments 
For consistency with normal instructions and clarity when reading IR,
it's best to print the %0, %1, ... names of function arguments in
definitions.

Also modifies the parser to accept IR in that form for obvious reasons.

Mehdi Amini 557c20a886 Remove compile time PreserveName in favor of a runtime cc1 -discard-value-names option 
Summary:
This flag is enabled by default in the driver when NDEBUG is set. It
is forwarded on the LLVMContext to discard all value names (but
GlobalValue) for performance purpose.

This an improved version of D18024

Daniel Sanders aa1b35590f [mips] Mark aggregate arguments passed in registers with the inreg attribute 
Summary:
This allows us to easily identify them in the backend which in turn allows us
to handle them correctly for big-endian targets (where they must be shifted
into the upper bits of the register).

Depends on D5961

Daniel Sanders 5b445b3844 [mips] Promote all integral/enumeration types to the GPR width 
Summary:
Ensure all integral/enumeration types are appropriately annotated with
signext/zeroext. In particular, i32 now has these attributes when using the
N32/N64 ABI. This paves the way for accurately representing the way the
N32/N64 ABI's promotes integer arguments to i64.

Anna Zaks 0f424b029b Revert "Add more attributes from the command line to functions." 
This reverts commit 176009.

The commit is a likely cause of several buildbot failures.

This is an ongoing process. Any command line option which a back-end cares about

Rafael Espindola fc3fc0c936 The clang driver has a fairly fancy support for executing gcc instead of 
clang itself. This dates back to clang's early days and while it looks like
some of it is still used (for kext for example), other parts are probably dead.

Remove the -ccc-clang-archs option and associated code. I don't think there
is any remaining setup where clang doesn't support an architecture but it can
expect an working gcc cross compiler to be available.

A nice side effect is that tests no longer need to differentiate architectures
that are included in production builds of clang and those that are not.

Akira Hatanaka e1e3ad3d11 Make the following changes in the way Mips handles vector arguments and return 
values:

- Return integer vectors in integer registers.
- Pass vector arguments in integer registers.
- Set an upper bound for argument alignment. The largest alignment is 8-byte
  for O32 and 16-byte for N32/64.
