Andre Kempe	861285c146	arm64: Fix wrong BTI landing pad This patch fixes a wrong type of BTI landing pad when branching to functions instantiated via the fft*_neon macro. Although the previously employed paciasp instruction serves as a landing pad, for the ways that this function is invoked it is the wrong type, resulting in an unexpected termination of the running process.

Andre Kempe	248986a0db	arm64: Add Armv8.3-A PAC support to assembly files This patch adds optional support for Arm Pointer Authentication Codes. PAC support is turned on or off at compile time using additional compiler flags. Unless any of these is enabled explicitly, no additional code will be emitted at all.

Jonathan Wright	08b4716a9e	aarch64: Add Armv8.5-A BTI support Add Branch Target Identifiers (BTIs) to all functions defined in AArch64 assembly files. Most of the BTI landing pads are added automatically by the 'function' macro. BTI support is turned on or off at compile time based on the presence of the __ARM_FEATURE_BTI_DEFAULT feature macro. A binary compiled with BTI support can be executed on an Armv8-A processor without BTI support because the instructions are defined in NOP space.

Martin Storsjö	780cd20b00	aarch64: Use .data.rel.ro for const data with relocations This reverts commit `c00365b46d` in addition to using a different section. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	c00365b46d	aarch64: Make the function pointer tables position independent This allows running the code on android, where 64 bit binaries with text relocations aren't allowed to be loaded. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Janne Grunau	ac6b95dbc0	aarch64: add ',' between assembler macro arguments where missing llvm's integrated assembler does not accept spaces as macro argument delimiter when targeting darwin. Using a explicit delimiter is a good idea in principle since it makes case like 'macro 4 -2' vs 'macro 4 - 2' clear.	10 years ago
Janne Grunau	9aa4592076	aarch64: assembler in clang-3.4 ignores the division by two Values are positive powers of two, so just replace it with right shift.	11 years ago
Janne Grunau	650c4300d9	aarch64: NEON float FFT Approximately as fast as the ARM NEON version on Apple's A7.	11 years ago
