With apple tools, the linker fails with errors like these, if the
offset is negative:
ld: in section __TEXT,__text reloc 8: symbol index out of range for architecture arm64
This is cherry-picked from libav commit
c44a8a3eabcd6acd2ba79f32ec8a432e6ebe552c.

arm64: add cycle counter support
Merged-by: Hendrik Leppkes <h.leppkes@gmail.com>
|
|
The ISB (instruction synchronization barrier) might be too heavy for
START/STOPTIMER use but should be more accurate in checkasm where the
timing overhead is subtracted.

aarch64: add darwin style PAGE/PAGEOFF relocations
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
Not supported by Clang's integrated assembler. Since it just adds
debug information it can safely omitted.
|
|
Both gnu as and clang treat lines starting with '#' as comments if they
aren't consumed by the C-style preprocessor.
Using '//' does not work with clang since comments are removed before
macro expansion.
|
|
Clang's integrated assembler does not support it.

aarch64: Use the correct syntax for relocations
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
This fixes building in PIC mode with gas. The examples in the gas
manual showed using a # here even though gas itself actually didn't
support that syntax (and the gas test suite only tests it without
the extra hash sign).

Ported from arm NEON and added vector_dmul_scalar.
Functions between 1.5 and 5 times faster than the C implementations
using Apple's clang-503.0.19 on A7.

aarch64: add cpuflags support for NEON and VFP
Merged-by: Michael Niedermayer <michaelni@gmx.at>
|
|
|
|
NEON and VFP are currently mandatory for all ARMv8 profiles. Both are
handled as extensions as far as cpuflags are concerned. This is
consistent with handling x86_64 which always has SSE2, but still
handles it as an extension.
