config CC_GCC_ENABLE_TARGET_OPTSPACE
bool
prompt "Optimize gcc libs for size"
default y
help
Pass --enable-target-optspace to crossgcc's configure.
This will compile crossgcc's libs with -Os.

config CC_CXA_ATEXIT
bool
prompt "Use __cxa_atexit"
default y
depends on ! BARE_METAL
help
If you get the missing symbol "__cxa_atexit" when building C++ programs,
you might want to try disabling this option.
config CC_GCC_DISABLE_PCH
bool
prompt "Do not build PCH"
default n
help
Say 'y' here to not use Pre-Compiled Headers in the resulting toolchain.
at the expense of speed when compiling C++ code.
For some configurations (most notably canadian?), PCH are broken, and
need to be disabled. Please see:

# This config option is used nowhere in the code on purpose.
# It only serves as a choice entry to force neither using nor not using sjlj
config CC_SJLJ_EXCEPTIONS_CONFIGURE
bool
prompt "Let configure decide"
help
Let configure decide if setjmp/longjmp should be used to handle
exceptions.
Choose that if you trust configure to detect the correct settings.
This is the default choice.
config CC_SJLJ_EXCEPTIONS_USE
bool
prompt "Force using sjlj"
help
Do use setjmp/longjmp for exceptions.
This is gcc's --enable-sjlj-exceptions configure switch.
Choose that if you want to use setjmp/longjmp to handle exceptions.
config CC_SJLJ_EXCEPTIONS_DONT_USE
bool
prompt "Force not using sjlj"
help
Do not use setjmp/longjmp for exceptions.
This is gcc's --disable-sjlj-exceptions configure switch.
Choose that if you want to not use setjmp/longjmp to handle exceptions.
