When did this happen? annotate is your friend. It's over 10 years old: Working file: /home/jhb/work/freebsd/svn/head/sys/sparc64/include/ucontext.h ------------------------------------------------------------------------ r105733 | jake | 2002-10-22 14:03:15 -0400 (Tue, 22 Oct 2002) | 13 lines - Expand struct trapframe to 256 bytes, make all fields fixed width and the same size. Add some fields that previously overlapped with something else or were missing. - Make struct regs and struct mcontext (minus floating point) the same as struct trapframe so converting between them is easy (null). - Add space for saving floating point state to struct mcontext. This requires that it be 64 byte aligned. - Add assertions that none of these structures change size, as they are part of the ABI. - Remove some dead code in sendsig(). - Save and restore %gsr in struct trapframe. Remember to restore %fsr. - Add some comments to exception.S. ------------------------------------------------------------------------ -- John BaldwinReceived on Thu Jul 11 2013 - 15:41:21 UTC
