premake5.lua

--[[
To generate Visual Studio files (in vs2019/ or vs2022/ directory), run:
scripts\premake-regenerate-vs-projects.ps1

I'm using premake5 beta1 from https://premake.github.io/download.html#v5

Note about nasm: when providing "-I foo/bar/" flag to nasm.exe, it must be
"foo/bar/" and not just "foo/bar".

Notes about asan in msvc: https://devblogs.microsoft.com/cppblog/addresssanitizer-asan-for-windows-with-msvc/

Reference for warnings:
 4018 - signed/unsigned mismatch
 4057 - function X differs in indirection to slightly different base types
 4090 - different 'const' qualifiers
 4091 - 'typedef ': ignored on left of 'tagGPFIDL_FLAGS' when no variable is declared
 4100 - unreferenced formal parameter
 4127 - conditional expression is constant
 4131 - uses old-style declarator
 4189 - local variable is initialized but not referenced, defer macro triggers this
 4204 - non-standard extension: non-constant aggregate initializer
 4206 - non-standard extension: translation unit is empty
 4244 - 64bit, conversion with possible loss of data
 4245 - sign/unsigned mismatch
 4267 - 64bit, conversion with possible loss of data
 4302 - 64bit, type cast truncation
 4305 - 'initializing': truncation from 'double' to 'float'
 4310 - 64bit, cast truncates constant value
 4311 - 64bit, type cast pointer truncation
 4312 - 64bit, conversion to X of greater size
 4324 - 64bit, structure was padded
 4458 - declaraion of X hides class member
 4522 - multiple assignment operators specified
 4530 - exception mismatch
 4611 - interaction between '_setjmp' and C++ object destruction is non-portable
 4702 - unreachable code
 4706 - assignment within conditional expression
 4800 - forcing value to bool (performance warning)
 4819 - The file contains a character that cannot be represented in the current code page
 4838 - conversion from X to Y requires a narrowing conversion
 4996 - POSIX name deprecated

 Linker warning
 4221 - This object file does not define any previously undefined public symbols, so it will not be used by any link operation that consumes this library

Prefast:
 28125 - function X must be called in try/except (InitializeCriticalSection)
 28252 - Inconsistent annotaion
 28253 - Inconsistent annotaion
