347309 - Building with --enable-leaky on PPC fails

Status: RESOLVED WONTFIX

(Firefox Build System :: General, defect)

Description

[Gopal Venkatesan]

User-Agent:       Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.8.1b1) Gecko/20060720 BonEcho/2.0b1
Build Identifier: Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.8.1b1) Gecko/20060720 BonEcho/2.0b1

Building Mozilla with --enable-leaky fails on powerpc (PPC) platforms because of an undefined function "CrawlStack".
This is because, for PPC, the function is not defined, as per the following in tools/leaky/libmalloc.cpp (line 101):

--- code ---
#if defined(i386)
static void CrawlStack(malloc_log_entry* me, jmp_buf jb)
{
// ... stuff
...
#endif

Either there should be a dummy entry for the function in other platforms, or a better way is to modify the configure script to flag an error indicating "leaky" is available only for x86 platforms.

if [ $MOZ_LEAKY -ne 1 ]
then
    test `uname -m` = i386 ||
        (echo '--enable-leaky option can be set only for x86 machines' 1>&2; exit 1)
fi


Reproducible: Always

Steps to Reproduce:
1. Try to build Mozilla with --enable-leaky on non x86 machines
2.
3.

Actual Results:  
Compiler complains about non existing function "CrawlStack" while trying to build tools/leaky.


Expected Results:  
configure should have warned initially and aborted indicating "leaky" cannot be built for non x86 platforms.

Can reporter please advise if fault still exists with recent Firefox version.

we no longer support PPC anyway.  (I don't know if we still support leaky, either!)
