Implement microMIPS 16-bit unconditional branch instruction B.
Implemented 16-bit microMIPS unconditional instruction has real name B16, and
B is an alias which expands to either B16 or BEQ according to the rules:
b 256 --> b16 256 # R_MICROMIPS_PC10_S1
b 12256 --> beq $zero, $zero, 12256 # R_MICROMIPS_PC16_S1
b label --> beq $zero, $zero, label # R_MICROMIPS_PC16_S1

llvm-svn: 226577
Add header guards to files that were missing guards. Remove #endif comments
as they don't seem common in LLVM (we can easily add them back if we decide
they're useful)
Changes made by clang-tidy with minor tweaks.

This patch provides support for the MIPS relocations:
*) R_MIPS_GOT_HI16
*) R_MIPS_GOT_LO16
*) R_MIPS_CALL_HI16
*) R_MIPS_CALL_LO16
These are used for large GOT instruction sequences.

These 2 relocations gain access to the
highest and the second highest 16 bits
of a 64 bit object.
R_MIPS_HIGHER %higher(A+S)
The %higher(x) function is [ (((long long) x + 0x80008000LL) >> 32) & 0xffff ].
R_MIPS_HIGHEST %highest(A+S)
The %highest(x) function is [ (((long long) x + 0x800080008000LL) >> 48) & 0xffff ].
llvm-svn: 161348
is used in cases where global symbols are
directly represented in the GOT and we use an
offset into the global offset table.
This patch adds direct object support for R_MIPS_GOT_DISP.
llvm-svn: 160183
It takes advantage of r159299 which introduces relocation support for N64.
elf-dump needed to be upgraded to support N64 relocations as well.
This passes make check.
