2 years agofix: teach Smyrna '-?' on macOS and Windows

fix: teach Smyrna '-?' on macOS and Windows

Matthew Fernandez [Mon, 21 Mar 2022 15:09:55 +0000 (08:09 -0700)]
smyrna Init: squash -Wincompatible-pointer-types

OpenGL has an unorthodox API wherein the `gluTessCallback` function’s prototype
indicates it takes a `void(*)(void)`, but its docs¹ explain that the type
actually varies depending on the second argument. As a result, the compiler
(correctly) warns that some of these `gluTessCallback` calls are passing
function pointers that do not have the same ABI. Presumably this works out
because at the end of the day a function pointer is just some bits in C and the
OpenGL implementation branches on the `which` argument and invokes the pointer
correctly. But if OpenGL really wanted to discard type safety this way, it is
not clear to me why they did not make the function pointer argument a `void*`.
Anyway, this commit squashes the compiler warnings which emerge when enabling
this in the CMake build system, failing the build.

cgraph: implement memory allocation wrappers

This change replicates and extends the exit-on-failure allocation wrappers from
lib/common/memory.c into a header-only implementation in cgraph. The existing
common wrappers worked but there were two limitations preventing their wider
use:

  1. lib/common is not the base of the Graphviz dependency graph. E.g.
     lib/cgraph does not depend on lib/common, preventing calling
     lib/common/memory.h functions from cgraph code. lib/cgraph is not the base
     of the dependency graph either (it depends on lib/cdt), but it has become a
     de facto home for header-only implementations of general utility functions
     called throughout the rest of the Graphviz code base.

  2. lib/common is not linked against by every Graphviz component. This meant
     other code could attempt to call functions in lib/common/memory.h but would
     fail to link because it was not pulling in lib/common/memory.c.

Relocating these functions neatly solves both the above two. It also has the
side effect of allowing compilers to inline these short wrappers. This could
(and would) previously be achieved with Link-Time Optimization, but now a
regular optimizing compilation can also achieve this.

Future changes will remove the lib/common/memory.c wrappers in favor of these.
