I deleted https://github.com/loongson/musl directory due to company's regulations. and attached 0001-add-loongarch64-port-v6.patch again in the email. Based on the v6 patch,I Modified the member names of struct sigcontext to maintain consistency with kernel and glibc. As shown in 0001-Modify-the-member-names-of-struct-sigcontext-in-loon.patch. The reason is that some application reference the mcontext structure member of glibc, When they link to musl, there is a compile error listed below because of the difference of the member name of mcontext between glibc and musl. Furthermore, we found that they also inconsistent with the kernel definition. so we want to unify them in the early stage. sigsegy.c:178:72:error:'mcontext_t’ {aka 'struct sigcontext"} has no member named'__gregs'
 define SIGSEGV_FAULT_STACKPOINTER ((ucontext_t*）ucp)->uC_mcontext.-_gregs[3] In addition, I found the member __pad of struct stat also has the same problem.so I modified __pad to __pad1 to maintain consistency with kernel and glibc.even if the __pad may not be referenced by anyone. As shown in 0002-Modify-the-member-__pad-of-struct-stat-to-__pad1-in-.patch. --------------6B2F21903697679E3353ED18 Content-Type: text/x-patch; charset=UTF-8; name="0001-add-loongarch64-port-v6.patch" Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename="0001-add-loongarch64-port-v6.patch" >From b42d9d9b749f0bbbe59e2b655131a7cb80473682 Mon Sep 17 00:00:00 2001 From: wanghongliang Date: Tue, 15 Nov 2022 03:44:52 +0800 Subject: [PATCH] add loongarch64 port v6.
