Thank you all for these details. It is my first deep journey in the
toolchain world, and as described on the ct-ng website, it can quickly
become a nightmare.
I was wrong when thinking the flags I used to build the toolchain were
thereafter implicitly enabled by default by the gcc toolchain.
I guess my CCX_FLAGS is then a non-sense :
CT_CC_ENABLE_CXX_FLAGS="-O3 -fstrict-aliasing -Wdouble-promotion -Wno-error
-Wunsafe-loop-optimizations -funsafe-loop-optimizations
-floop-nest-optimize -floop-parallelize-all -fsanitize=thread
-fsanitize=address"
The toolchain still built fine and works.. Shall I build a new one with
less (or no) flags? In case keeping my actual one, can all these flags lead
to some potential issues later? Which flags would you keep ?
My toolchain is aimed at building android kernel and rom for the Google LG
nexus 4. I am not sure of some of my settings, so I would appreciate any
advice.
mfpu=neon ===> or vfpv3-d16, vfpv4-d16, neon-vfpv4, neon-fp16 ??
CPU="cortex-a9" =====> or cortex-a15 ?? I saw nexus4 kernel are built with
the -a15 instruction
LIBC_ADDONS_LIST=" libidn " ====> or not ? I don't understand fully this
lib.
Please find below my actual config. As mentioned above, it builds and
works, but I am far from being sure I used the correct setiings.
