- Subject: [PATCH v4 00/13] port C-SKY to glibc
It is the fourth patchset for C-SKY port. Base on commit
38245425a9add7bd22f8732219e0085432f223b6 (6 sep). Two abi combinations
are supported with this patch: C-SKY ABIV2 with (soft float & little endian,
hard float & little endian). CK807(ef), CK810(ef), CK860 are the
accroding supported processor cores to the C-SKY V2 abi;
f stands for FPU co-processor; e stands for DSP co-processor. Our
gcc and binutils support have already been merge to the gnu trunck.
The fourth linux csky support patchset has been post to kernel.org last
week, seems will ready in several weeks. This patchset is tested
with gcc(9.0), binutil(2.31), linux(4.18), GCC and Binutils are from
the official respository:
1. GCC commit:
be2d111a878e1422c921226bc7714131a5c470fa
2. Binutils commit:
316828699127cc855cf06cbfaee096f6fa75bba4
3. Linux git repo path

CSKY architecture user guide:
https://github.com/c-sky/csky-doc/blob/master/CSKY%20Architecture%20user_guide.pdf
IFUNC, ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA, static PIE is not support
with this patchset.
Several patches will be post to GCC and Binutils to fix some testcase fail
later this month, while the follow results have these patches applied.
The patchset is cross-tested with qemu system mode as I have no board
with enough memory or can caculate subnormal.

FAIL cases:
1. nptl/tst-thread_local1
seems lack c++ support, the gcc frountend can not generate constructor
and destructor for static, anonymous_namespace and extern variables.
2. sunrpc/bug20790
It fails because the testing environment lacks native cpp.
3. malloc/tst-malloc-usable-tunables
It fails because liunx use mmap to alloc space for vdso and cause brk
fail. Wait for our linux kernel to fix it.
4. nptl/tst-_res1
It fails because symbol _res is incorrect linked.
5. The following cases fail due to gcc optimize change the sequence of
-a * b to -(a * b) and got 1ulps error.
math/test-double-tgamma
math/test-float-tgamma
math/test-float32-tgamma
math/test-float32x-tgamma
math/test-float64-tgamma
math/test-ldouble-tgamma
6. The following three cases some time get into deadlock when the child
return before the parent thread start to wait. I don know what is
the expect behaviour under this condition.
misc/tst-clone3
tst-mallocfork
tst-mallocfork2

- update the abilist
- update ulps
- cleanup unnecessary linux syscall
- remove support for ABIV1
- add one-line description for many files
- put ABIV2 code into seperate folder

- cleanup linux/csky/Version
- add with_fp_cond support to distinguish soft float
- remove PF_X in stackinfo
- add abi check in preconfigure
- support build-many-glibcs.py
- fix pointer guard acquisition
Changes since v1:
- update the changelog format
- clean up unnecessary legacy code and odd comments
- add rel description and fix EM_CSKY check
