Hi,
where could we find which options are passed to GCC? I mean -mcpu -mtune, -mfloat, etc.
Most of it is defined in gcc. You can call it with some magic parameter to have it tell you :). The rest are RPM_OPT_FLAGS which should be in the prjconf meta of the project.
gcc -v gives configure options used to build GCC. I guess it is this command to use. RPM_OPT_FLAGS does not give much, only:
-fmessage-length=0 -O2 -Wall -D_FORTIFY_SOURCE=2 -fstack-protector -funwind-tables -fasynchronous-unwind-tables -g
Currently, I think we are using the following for ARM v7, but I cannot find where it is defined: * thumb2
Only for factory. 12.2 builds with -marm.
ok.
* VFPV3-d16 * tune: cortex-A9
Those 2 are correct.
Thanks.
Should we document it in the wiki?
In an ideal world, most certainly yes :)
