MEMPROFILE is broken

[MaheshWaidande]

Hi All,

I am working on building/porting Julia on ppc64le architecture. I am using Ubuntu 14.10 on top of ppc64le hardware, while compiling Julia code (master branch) I was getting segmentation fault, I am able to resolve this segmentation fault by turning on MEMDEBUG flag from src/options.h file.

I decided to work more this issue and try to find out root cause of segmentation fault, so I started studying/understanding memory management scheme of Julia.

To understanding GC and de-allocation mechanism I turn on profiling options MEMPROFILE, GC_TIME from options.h file (by default they are commented out I uncomment those) but when I try to compile code with these profiling flags on julia compilation (make debug) gets failed.

Below compilation errors I observed after enabling,

1. GC_TIME flag

   gc.c:237:26: error: current_heap undeclared (first use in this function)
    #define HEAP(x) (*((void)current_heap,&(x)))
   

2. MEMPROFILE flag

   gc.c:2414:21: error: pool_t has no member named pages
   

My Machine details are:
Linux 3.16.0-30-generic #40-Ubuntu SMP ppc64le ppc64le ppc64le GNU/Linux

MEMPROFILE has been broken for some time IIRC. Feel free to make it work again once you've figured out the allocator :-)
The output always was a bit unreadable anyway.
