I feel I missed a train.
Yoshii, are you able to try with older gcc ? ...
I built gcc-3.4.6 for testing, but none older than it.
... or was you able to produce \n a testcase ?
No.
I couldn't find nothing other than CRT_CALL_STATIC_FUNCTIONs between
this prologue and epilogue, which is
Thank you for your review.
I've found some of architectures other than SH set a pointer to _dl_fini()
to rtld_fini in ldso/ldso/*/dl-startup.h, which apparently SH should have, too.
I've add small patch. Though I am really not confidence of correctness
This one set the pointer to _dl_init()
Hi,
please find attached another patch to completely fix the sh4 startup
sequence (in addition to the patch of Yoshii).
Tested. It works fine here. Great.

This still requires the kernel zeroing the r4 value before handing
control over as per your FLAT_PLAT_INIT() patch, correct?
Yes. I think kernel should set(clear) r4 for static object(ELF and FLT).
For shared one(currently ELF), dl-start.h(uClibc)/dl-machine.h(glibc) set r4.
# Perhaps the real
Hi,
Hum... I think that we are lucky because _dl_fini is defined in ldso.c
that includes dl-startup.c that includes dl-startup.h... but if _dl_fini
were defined in another compilation units ? does it work ? am I correct ?
Well, that strange structure of the source code tells us that this
Hi,
As a comment in libc/sysdeps/linux/sh/crt1.S says
/* __uClibc_main (main, argc, argv, init, fini) */
, something wrong here. There should be two more args.
7th arg stack_end seems to be missing.
6th one is not listed, but the original code pushed register r4 here.
It is not
