musl/src/thread/microblaze/clone.s, branch v1.2.6 musl - an implementation of the standard library for Linux-based systems clone: clear the frame pointer in the child process on relevant ports 2025-02-22T01:53:41+00:00 Alex Rønne Petersen alex@alexrp.com 2024-12-12T16:56:04+00:00 b6b81f697b38ef915a5dbf1311baba164822e917 This just mirrors what is done in the start code for the affected ports, as well as what is already done for the three x86 ports. Clearing the frame pointer helps protect FP-based unwinders from wrongly attempting to traverse into the parent thread's call frame stack.

Clearing the frame pointer helps protect FP-based unwinders from
wrongly attempting to traverse into the parent thread's call frame
stack.

clone: make clone a wrapper around __clone 2014-02-10T02:07:43+00:00 Bobby Bingham koorogi@koorogi.info 2014-02-07T04:11:22+00:00 fdf5f1b13123883ac1d5e298e5f32c7ed43578ce The architecture-specific assembly versions of clone did not set errno on failure, which is inconsistent with glibc. __clone still returns the error via its return value, and clone is now a wrapper that sets errno as needed. The public clone has also been moved to src/linux, as it's not directly related to the pthreads API. __clone is called by pthread_create, which does not report errors via errno. Though not strictly necessary, it's nice to avoid clobbering errno here.
