ftrace: Make CALLER_ADDRx macros more generic

2014-05-21T07:10:32+00:00

Most archs with HAVE_ARCH_CALLER_ADDR have pretty much the same definitions of CALLER_ADDRx(n). Instead of duplicating the code for all the archs, define a ftrace_return_address0() and ftrace_return_address(n) that can be overwritten by the archs if they need to do something different. Instead of 7 macros in every arch, we now only have at most 2 (and actually only 1 as ftrace_return_address0() should be the same for all archs). The CALLER_ADDRx(n) will now be defined in linux/ftrace.h and use the ftrace_return_address*(n?) macros. This removes a lot of the duplicate code.

Blackfin: add CALLER_ADDR ftrace macros

2010-03-09T05:30:50+00:00

Since GCC doesn't support __builtin_frame_address(n) where n!=0, add our own function to walk the stack frame pointers. Signed-off-by: Yi Li Signed-off-by: Mike Frysinger

Blackfin: update ftrace for latest toolchain

2009-09-17T02:10:52+00:00

The mcount support that was finally added to the Blackfin gcc port isn't exactly the same as what ftrace was developed against. Now that the final gcc version is in place, update the ftrace code to match. While updating this, fix the swapped arguments to the tracer (signature is (ip, parent_ip) while we were passing (parent_ip, ip)). Signed-off-by: Yi Li Signed-off-by: Mike Frysinger

Blackfin: initial support for ftrace

Just the basic ftrace support here -- mcount and the ftrace stub. Signed-off-by: Mike Frysinger

tracing: make CALLER_ADDRx overwriteable

2009-03-02T21:49:37+00:00

The current definition of CALLER_ADDRx isn't suitable for all platforms. E.g. for ARM __builtin_return_address(N) doesn't work for N > 0 and AFAIK for powerpc there are no frame pointers needed to have a working __builtin_return_address. This patch allows defining the CALLER_ADDRx macros in and let these take precedence. Because now is included unconditionally in all archs that don't already had this include get an empty one for free.
