Hi,
This is a start at warning about various resource allocation issues that can be
improved. Currently it only warns about functions that call malloc and then
always pass the resulting pointer to free().
It should be pretty simple to extend this to new/delete and new[]/d
Hello world,
the attached patch goes one step further in matmul inlinding.
It converts statements like
r = dot_product(matmul(a2,v1),v2)
into
tmp = matmul(a2,v1)
r = dot_product(tmp,v2)
to enable inlining of matmul (but only if inlining
is active, of course).
In order to detect multip

Hi all,
On FreeBSD we make use of the functions _Unwind_GetIP, _Unwind_GetIPInfo
and _Unwind_SetIP outside of GCC. All other FreeBSD targets have these
functions available except arm.
Now since the GCC port for arm*-*-freebsd* is used more often (not only

Hi all,
I'm going to commit the below patch to all active branches. (8,7,6,5)
It makes arm*-*-freebsd* use the generic FreeBSD t-slibgcc-elf-ver
definition. This makes all FreeBSD targets 'consistent' in this area.
If not ok, please speak up soon.
TIA,
