Bug ID: 89955
Summary: riscv.h improperly defines STARTFILE_PREFIX_SPEC spec
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target
Assignee: unassigned at gcc dot gnu.org
Reporter: kallisti5 at unixzen dot com
Target Milestone: ---
https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/config/riscv/riscv.h?view=markup#l885
gcc/config/riscv.h defines STARTFILE_PREFIX_SPEC which breaks sysroot's.
Under a new platform (Haiku), our bootstrap was failing missing core existing
cross-compiled system libraries which were present and accounted for.
Eventually I figured out to #undef STARTFILE_PREFIX_SPEC in our
gcc/config/riscv/haiku.h header and things magically began working. Since
we're cross compiling with a sysroot (which is *not*) at /usr/lib,/lib,etc, it
breaks the sysroot functionality.
Likely I think STARTFILE_PREFIX_SPEC needs moved to config/riscv/linux.h ?
