emulate the addition of NETBSD_SUBTARGET_EXTRA_SPECS usually done by
SUBTARGET_EXTRA_SPECS (not used in risc-v) with EXTRA_SPECS.
Go back to using %(netbsd_link_spec) in our link spec, now that it's
a valid string.
Try to mimic other riscv OSes in our LINK_SPEC. they all start with
"-melf" XLEN_SPEC "lriscv" LD_EMUL_SUFFIX
and a definition of LD_EMUL_SUFFIX,
let's copy the LD_EMUL_SUFFIX linux uses.
Now we can link executables.
UINTMAX_TYPE / INTMAX_TYPE are mostly not redefined on netbsd.
These choices contradict typical 64bit archs, perhaps we don't want them.
XXX is the SIZE_TYPE default for riscv reasonable?
(long unsigned int for 64bit abi, unsigned int for 32bit abi)
My current guess as to why it makes a difference is that riscv, unlike other
targets, doesn't use the macro SUBTARGET_EXTRA_SPECS for anything meaningful
Fixes linking libgcc_s.so, which is now emitted as a dynamic library, not
a static object (which fails, as it has undefined references)
XXX there might be a better way of doing this
(Architecture list taken from src/tests/libexec/ld.elf_so/t_ifunc.c)
This is needed for attribute target_clones to work.
Non-functional until a mknative run. Tested by doing a regular GCC build.
note vax atf fails same as GCC 6. hppa mostly works but has an
atf issue also unrelated to the compiler version
note ia64 mostly builds, but the kernel fails earlier than GCC 6.
symbols classified as local in pic mode, and that ends up with PC32
relocations "movl *psp, %rx" (/bin/sh parse.c). Treat pic code as
shared libraries to avoid classifying common initialized symbols
as local. Thanks to thorpej@ for his help.
unfortunately, we attempted to do this for netbsd-8 but we did
not actually end up having any ABI incompatibility with that,
as turning off dual ABI in libstdc++ means *only* enabling the
old ABI. however, enabling dual ABI with C11 defaults (ie,
a forward looking ABI) *is* an ABI-change for some special
cases and thus we should have bumped this a couple of weeks
ago when we re-enabled dual ABI.
call this "nb3 20190319".
mknative-gcc regen all switched ports and almost all of the
unswitched ports.
duplicate symbols on netbsd. see PR#54027.
with this disabled, turn on using the symver-config.h for the
gnu.ver processing so that other defines are handled.
fix some depends for gnu.ver processing.
