### Assembler and disassembler
* Based on Revision 31 of SPIR-V
-* All core instructions are supported, except:
- * Changes to operand enum values and their syntax since Rev 30 will not work.
- * Image operands (section 3.14) are not supported, for example.
- * Test coverage is very limited.
+* Assembler supports all core instructions, for 32-bit code.
+ * Handling of non-32-bit literal numbers has been recently clarified.
+ Those changes have not been applied.
* All GLSL std450 extended instructions are supported.
* Assembler only does basic syntax checking. No cross validation of IDs or
types is performed.
