janneke pushed a commit to branch wip-arm-bootstrap
in repository guix.
commit cc625c9b1edb3878cacb421d2645fb95d001dd10
Author: Jan (janneke) Nieuwenhuizen <janneke@gnu.org>
AuthorDate: Tue Dec 28 15:53:19 2021 +0100
DRAFT gnu: commencement: glibc-mesboot0: Support ARM.
* __restrict_arr is probably symptom of preprocessor arithmetic problems
+ lsh, /
* It looks like glibc-2.2.5 and mesboot-haeders mismatch.
+ Many __NR_* syscalls are missing
+ Some headers are missing.
* gcc-mesboot0: illegal instruction in glibc-2.2.5:
0x000276b4 <+28>: ldr r8, [r10]
0x000276b8 <+32>: svc 0x00000014
=> 0x000276bc <+36>: mov r4, r0
* gnu/packages/patches/glibc-bootstrap-arm-2.2.5.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/commencement.scm (glibc-mesboot0)[native-inputs]: Add it.
[arguments]: Apply it in apply-patches. Cater for armhf-linux,
aarch64-linux.
* gnu/packages/commencement.scm (glibc-mesboot0)
[supported-systems]: Add armhf-linux, aarch64-linux.
