This is mainly a maintaince commit which syncs changes between Blender and Libmv upstream also bringing new GLog version. This GLog version is presumably have better support of MinGW from "the box". This commit is also aimed to make further 3d part libs update easier.

// 1) The libunwind library. This is still in development, and as a
|
|
// separate library adds a new dependency, but doesn't need a frame
|
|
// pointer. It also doesn't call malloc.
|
|
//
|
|
// 2) Our hand-coded stack-unwinder. This depends on a certain stack
|
|
// layout, which is used by gcc (and those systems using a
|
|
// gcc-compatible ABI) on x86 systems, at least since gcc 2.95.
|
|
// It uses the frame pointer to do its work.
|
|
//
|
|
// 3) The gdb unwinder -- also the one used by the c++ exception code.
|
|
// It's obviously well-tested, but has a fatal flaw: it can call
|
|
// malloc() from the unwinder. This is a problem because we're
|
|
// trying to use the unwinder to instrument malloc().
|
|
//
|
|
// Note: if you add a new implementation here, make sure it works
|
|
// correctly when GetStackTrace() is called with max_depth == 0.
|
|
// Some code may do that.
