Chris Lattner 332673d39d From his comment in PR12168, Eli seems confused about the alignment assumptions 
we're making.  We only ignore implicit casts.  Add a testcase showing that
we get the right behavior with explicit casts.

Benjamin Kramer 5aeee5f854 Shrink the asm matcher tables. 
- Shrink the opcode field to 16 bits.
- Shrink the AsmVariantID field to 8 bits.
- Store the mnemonic string in a string table, store a 16 bit index.
- Store a pascal-style length byte in the string instead of a null terminator,
  so we can avoid calling strlen on every entry we visit during mnemonic search.

Shrinks X86AsmParser.o from 434k to 201k on x86_64 and eliminates relocs from the table.

Eli Friedman 5358a0ab5a Avoid an unnecessary recursive loop between type canonicalization and NNS canonicalization which would (rarely) lead to memory corruption. While I'm here, simplify. Fixes PR12166. Not committing a testcase because it's impossible to reduce it.

Daniel Dunbar ae77b3dfad Frontend: Default to creating output files using temporary files + rename. 
- This is a more reliable default, as it behaves better on failure and also
   ensures that we create *new* files (instead of reusing existing inodes). This
   is useful for other applications (like lldb) which want to cache inode's to
   know when a file has been rewritten.

Daniel Dunbar b9c62c0773 Frontend: Don't automatically create missing directories when using temporary files with createOutputFile()

Richard Smith bc638767f8 Reinstate r151879, r151880, reverted in r151922, along with a bugfix for 
scalar emission of DeclRefExprs to const bools: emit scalar bools as i1,
not as i8.

In addition to the extra unit testing, this has successfully bootstrapped.

Anna Zaks fc5dfe9f7c [analyzer] Rename clang::CallGraph into clang::idx::CallGraph + rename 
the corresponding files to avoid confusion.

This is a preparation to adding an AST-based call graph to Analysis. The
existing call graph works with indexer entries. We might be able to
refactor it to use the AST based graph in the future.

(Minimal testing here as the only example that uses the API has been
completely broken, does not compile.)

Johnny Chen 213ba7c7c3 rdar://problem/10652076 
Add logic to GDBRemoteRegisterContext class to be able to read/write a "composite" register
which has "primordial" registers as its constituents.  In particular, Read/WriteRegisterBytes()
now delegate to Get/SetPrimordialRegister() helper methods to read/write register contents.

Also modify RegisterValue class to be able to parse "register write" string value for the
NEON quadword registers which is displayed as a vector of uint8's.

Example:

(lldb) register write q0 "{0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}"
(lldb) register read q0
q0 = {0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08 0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}
(lldb) register read --format uint8_t[] s0
s0 = {0x01 0x02 0x03 0x04}
(lldb) register read --format uint8_t[] d0
d0 = {0x01 0x02 0x03 0x04 0x05 0x06 0x07 0x08}
(lldb) register read --format uint8_t[] d1
d1 = {0x09 0x0a 0x0b 0x0c 0x0d 0x0e 0x0f 0x10}
