Reg. Stack allocation and profiling tools in X86

[Subramanian Ramaswamy]

Hi,

How is the heap and stack size allocated in X86? Do they start off at
both ends and keep coming towards each other as they grow as in MIPS?

If it is like above, is there any profiling tool that will help me
figure out the maximum stack size for benchmarks on X86, so I can filter
out all the stack references from the memory trace I plan to generate.

Really appreciate responses to the above questions.

Thanks,
Mani

You can watch the memory allocated to a process in
"/proc/<process_id>/maps" on Linux. X86 stacks grow down and the heap
(top of bss - set by brk) grows up. You also have mmap, which is used to
allocate arbitrary pages of memory.
