- Subject: stack allocation for sh64-elf
- Organization: SuperH UK Ltd.
I've found that a lot of c++ tests fail due to a lack of memory.
Half a megabyte is find for fine for a lot of C programs, but
anything linked against libstdc++-v3 with all its constructors
and destructors that pull in automatically large parts of the
library is just to bulky. Therefore, I want to make the stack
allocation configurable, like for sh-elf, with the attached patch.
I'm not sure if this will require a change for netbsd as well.
