[Valgrind-developers] Difference between VG_(malloc) and VG_(am_shadow_alloc)

[John A. <joh...@gm...>]

Hi,

I am still starting off with tool development and am digging through the
code and had a basic question: What is the difference between requesting
memory using VG_(malloc) and VG_(am_shadow_alloc)? I grepped through the
code and found that VG_(am_shadow_alloc) is a wrapper
for VG_(am_sbrk_anon_float_valgrind) but can't find how this is different
from VG_(malloc).

Thanks,
John
