ARMvX?

[BogDan]

Hi,

We are (should) using android's default (recommended) compilation flags, because we must 
On arm-v7a platform we are using vfp: -Wno-psabi -march=armv7-a -mfloat-abi=softfp -mfpu=vfp -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-short-enums 

On arm-v5 (also arm-v6) platforms we are NOT using vfp: -Wno-psabi -march=armv5te -mtune=xscale -msoft-float -fpic -ffunction-sections -funwind-tables -fstack-protector -fno-short-enums

Check ~/NecessitasQtSDK/android-ndk-r6/docs/CPU-ARCH-ABIS.html for more information.

Cheers,
BogDan.
