musl/src/thread/m68k, branch master 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.
