Hey
I'm trying to extend the *link: specs to pass a different
-dynamic-linker depending on the float ABI. But I didn't manage to
build a construct which would preserve the order of the flags; if I do
something like:
%{msoft-float:-dynamic-linker V1} %{mfloat-abi=softfp:-dynamic-linker V2}
Then I get V2 for "-mfloat-abi=softfp -msoft-float" instead of V1.
In gcc/gcc.c I found some docs on spec file syntax; I see one can use
%{S*&T*} and %{S*:X}, but apparently %{S*&T*:X} isn't allowed, so I
can't manipulate the value. I tried to use
%{msoft-float*:-dynamic-linker V1} %{mfloat-abi=softfp*:-dynamic-linker V2}
but that gives the same effect (the msoft-float flags are
grouped together in the original order and put first, then the
mfloat-abi=softfp are grouped together in the original order and put
second).
I didn't manage to get %{msoft-float*:%<msoft-float -dynamic-linker V1}
to work; in fact I didn't get supressions to work.
Any idea?
Thanks!
PS: float-abit=softfp/soft-float are just convenient examples; the
actual target is to use different -dynamic-linker for hard vs soft
float-abi
