Paul Pluzhnikov b56375e76a Reduce stack use and apply CONFIG_DEBUG_FRAME to more code. ... Currently, libunwind allocates several PATH_MAX entries on stack, while trying to find a binary via /proc/.../maps. However stack space may be at premium (especially when sigaltstack is used), and PATH_MAX on Linux is 4096, while SIGSTKSZ is only 8192 on x86. Attached patch eliminates multiple PATH_MAX stack allocations, and simplifies code in maps_next, at the cost of being unable to do anything if we can't mmap one page. It appears to me that under such low-memory conditions, libunwind will fail shortly elsewhere anyway. This patch also disables more of debug_frame-handling code when CONFIG_DEBUG_FRAME is undefined. Tested on Linux/x86_64 with and without CONFIG_DEBUG_FRAME, no regressions.		2009-10-07 12:51:03 -07:00
