| * arm: hpeldsp: prevent overreads in armv6 asmJanne Grunau2014-03-05
| | | | | | | | | | | | | | Based on a patch by Russel King <rmk+libav@arm.linux.org.uk> Bug-Id: 646 CC: libav-stable@libav.org

| * arm: Mark the stack as non-executableMartin Storsjö2014-02-19
| | | | | | | | | | | | | | If linking in an object file without this attribute set, the linker will assume that an executable stack might be needed. Signed-off-by: Martin Storsjö <martin@martin.st>

|\| | | | | | | | | | | | | * commit 'e3fec3f095ab5ea08ee662942d98526aaf5e3635': arm: Add EXTERN_ASM to the .func and .type declarations for exported symbols Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * arm: Add EXTERN_ASM to the .func and .type declarations for exported symbolsMartin Storsjö2014-02-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the generated assembly more internally consistent, avoiding declaring two labels for the same function (for cases where EXTERN_ASM is empty) and not declaring a separate unprefixed label in other cases. This also makes sure the .func and .type delcarations have the same prefix. They have previously not been used on the platforms that have prefixed symbols on arm (iOS), but gas-preprocessor has recently started using the .func declarations for adding .thumb_func declarations for such functions.

| * arm: Allow overriding the alignment set in the function macroMartin Storsjö2014-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function macro always sets .align 2 before declaring the function label (since 5c5e1ea3) and always sets the section to .text (since 278caa6a). The .align 5 before certain functions, added in fc252eba, were added before .text and .align were added to the function macro and thus became useless/unused when the function macro got them. This restores the original intention, to align the loop entry points. Signed-off-by: Martin Storsjö <martin@martin.st>

| * arm: Fall back to runtime cpu feature detection via /proc/cpuinfoMartin Storsjö2013-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On recent android versions, /proc/self/auxw is unreadable (unless the process is running running under the shell uid or in debuggable mode, which makes it hard to notice). See http://b.android.com/43055 and https://android-review.googlesource.com/51271 for more information about the issue. This makes sure e.g. neon optimizations are enabled at runtime in android apps even when built in release mode, if configured to use the runtime detection.
