Deliver is invoked to handle incoming requests. If the request returns false from IsNotify then the Handler must eventually call Reply on the Conn wit

Validates correctness of derivative instructions.

Destroys all of the elements in |small_data_| that have been constructed.

Returns true of there is an entry in |values_inserted| for every element of |Type|.

Returns true if |a| and |b| are instructions defining pointers that point to types logically match and the decorations that apply to |b| are a subset

Return true if |bb| is dominated by at least one block in |exits|

This rule look for a dot with a constant vector containing a single 1 and the rest 0s. This is the same as doing an extract.

Removes any OpPhi instructions in |block|, which should have exactly one predecessor, replacing uses of OpPhi ids with the ids associated with the pre

Returns capabilities that enable an opcode. An empty result is interpreted as no prohibition of use of the opcode. If the result is non-empty, then

Emits the graph postamble.

Returns the given graph end instruction.

Resolves internal references among the module, functions, basic blocks, etc. This function should be called after adding all instructions.

Execute a command using the shell. Returns true if and only if the command's exit status was 0.

Execute a command using the shell. Returns true if and only if the command's exit status was 0.

TODO - Make a common util if someone else needs it too outside this file

Returns whether the exit block of this construct is the merge block for an OpLoopMerge or OpSelectionMerge

When an FMix with is feeding an Extract that extracts an element whose corresponding |a| in the FMix is 0 or 1, we can extract from one of the operand

Helper function for FactorAddSubMuls. If |factor0_0| is the same as |factor1_0|, generate: |factor0_0| * (|factor0_1| + |factor1_1|) |factor0_0| * (|f

Filename returns the file path for the given URI. It is an error to call this on a URI that is not a valid filename.

Finds the fall through case construct of |target_block| and records it in |case_fall_through|. Returns SPV_ERROR_INVALID_CFG if the case construct hea

Helper method to find the fragment shader entry point, complaining if there is no shader or if there is no fragment entry point.

Helper to get the ids of float constants 0.0 and 1.0, creating them if necessary.

Helper method to check that there is a single vec4 output variable and get a pointer to it.

Fold OpSelect instructions which have constant booleans as their result. x ? true : false = x x ? false : true = !x

Folds an OpcompositeExtract where input is a composite constant.
