 Slang has preliminary support for `debugBreak()` intrinsic. With the appropriate tooling, when `debugBreak` is hit it will cause execution to halt and display in the attached debugger.
 
-Currently this is supported in all targets except HLSL. Note that on some targets if there isn't an appropriate debugging environment the debugBreak might cause execution to fail or potentially it is ignored.
+This is not supported on HLSL, GLSL, SPIR-V or Metal backends. Note that on some targets if there isn't an appropriate debugging environment the debugBreak might cause execution to fail or potentially it is ignored.
 
 On C++ targets debugBreak is implemented using SLANG_BREAKPOINT defined in "slang-cpp-prelude.h". If there isn't a suitable intrinsic, this will default to attempting to write to `nullptr` leading to a crash.
