Hello, I use the arm-hisiv600-linux-gcc for hisilicon soc chip. The output of arm-hisiv600-linux-gcc -print-multi-lib is: .; armv5te_arm9;@mcpu=arm926ej-s a9;@mcpu=cortex-a9 a7;@mcpu=cortex-a7 a17;@mcpu=cortex-a17 a17_a7;@mcpu=cortex-a17.cortex-a7 armv5te_arm9_soft;@mcpu=arm926ej-s@mfloat-abi=soft armv5te_arm9_vfp;@mcpu=arm926ej-s@mfloat-abi=softfp@mfpu=vfp a9_soft;@mcpu=cortex-a9@mfloat-abi=soft a9_softfp_vfp;@mcpu=cortex-a9@mfloat-abi=softfp@mfpu=vfp a9_softfp_vfpv3-d16;@mcpu=cortex-a9@mfloat-abi=softfp@mfpu=vfpv3-d16 a9_vfpv3;@mcpu=cortex-a9@mfloat-abi=softfp@mfpu=vfpv3 a9_vfpv3_neon;@mcpu=cortex-a9@mfloat-abi=softfp@mfpu=neon a9_hard_neon;@mcpu=cortex-a9@mfloat-abi=hard@mfpu=neon a7_soft;@mcpu=cortex-a7@mfloat-abi=soft a7_softfp_vfpv4;@mcpu=cortex-a7@mfloat-abi=softfp@mfpu=vfpv4 a7_softfp_neon-vfpv4;@mcpu=cortex-a7@mfloat-abi=softfp@mfpu=neon-vfpv4 a7_hard_neon-vfpv4;@mcpu=cortex-a7@mfloat-abi=hard@mfpu=neon-vfpv4 a17_soft;@mcpu=cortex-a17@mfloat-abi=soft a17_softfp_vfpv4;@mcpu=cortex-a17@mfloat-abi=softfp@mfpu=vfpv4 a17_softfp_neon-vfpv4;@mcpu=cortex-a17@mfloat-abi=softfp@mfpu=neon-vfpv4 a17_hard_neon-vfpv4;@mcpu=cortex-a17@mfloat-abi=hard@mfpu=neon-vfpv4 a17_a7_soft;@mcpu=cortex-a17.cortex-a7@mfloat-abi=soft a17_a7_softfp_vfpv4;@mcpu=cortex-a17.cortex-a7@mfloat-abi=softfp@mfpu=vfpv4 a17_a7_softfp_neon-vfpv4;@mcpu=cortex-a17.cortex-a7@mfloat-abi=softfp@mfpu=neon-vfpv4 a17_a7_hard_neon-vfpv4;@mcpu=cortex-a17.cortex-a7@mfloat-abi=hard@mfpu=neon-vfpv4 I want to change the gcc with a17_a7_hard_neon-vfpv4 which needs mcpu=cortex-a17.cortex-a7 mfloat-abi=hard mfpu=neon-vfpv4 options. The default gcc option is mfloat-abi=softfp How can i modify the specs file to use a17_a7_hard_neon-vfpv4? The output of arm-hisiv600-linux-gcc -print-multi-directory is: . How to change the specs file to make the output of arm-hisiv600-linux-gcc -print-multi-directory changes to a17_a7_hard_neon-vfpv4? Thanks!
