From ce7a3fdc5c55fd01d8e2deda0daef84473644f8b Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 15 Jun 2006 18:00:34 +0100 Subject: [PATCH] [ARM] Remove rt_sigframe puc and pinfo pointers These two members appear to be surplus to requirements. Discussing this issue with glibc folk: | > Additionally, do you see any need for these weird "puc" and "pinfo" | > pointers in the kernels rt_sigframe structure? Can we kill them? | | We can kill them. I checked with Phil B. about them last week, and he | didn't remember any reason they still needed to be there. And nothing | should know where they are on the stack. Unfortunately, doing this | will upset GDB, which knows that the saved registers are 0x88 bytes | above the stack pointer on entrance to an rt signal trampoline; but, | since puc and pinfo are quite recognizable, I can adapt GDB to support | the new layout if you want to remove them. So remove them.
