4 | Subject: [PATCH 40/49] Add ssp_nonshared to link commandline for musl targets | ||
5 | |||
6 | when -fstack-protector options are enabled we need to | ||
7 | link with ssp_shared on musl since it does not provide | ||
8 | the __stack_chk_fail_local() so essentially it provides | ||
9 | libssp but not libssp_nonshared something like | ||
10 | TARGET_LIBC_PROVIDES_SSP_BUT_NOT_SSP_NONSHARED | ||
11 | where-as for glibc the needed symbols | ||
12 | are already present in libc_nonshared library therefore | ||
13 | we do not need any library helper on glibc based systems | ||
14 | but musl needs the libssp_noshared from gcc | ||
15 | |||
16 | Upstream-Status: Pending | ||
