|\ | | | | | | | | | | | | * commit 'dcae2e32f7d8a1ca5fb8c1e4aa81313be854dd73': arm: Suppress tags about used cpu arch and extensions Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * arm: Suppress tags about used cpu arch and extensionsMartin Storsjö2015-03-07
| | | | | | | | | | | | | | | | | | | | When all the codepaths using manually set .arch/.fpu code is behind runtime detection, the elf attributes should be suppressed. This allows tools to know that the final built binary doesn't strictly require these extensions. Signed-off-by: Martin Storsjö <martin@martin.st>

| | | | | | | | | | Not supported by Clang's integrated assembler. Since it just adds debug information it can safely omitted.

| * 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>

References to external symbols should now use the movrelx macro. Some additional code changes are required since this macro may need a register to hold the GOT pointer.
