-# Generate the file opcodes.h. |
-# |
-# This TCL script scans a concatenation of the parse.h output file from the |
-# parser and the vdbe.c source file in order to generate the opcodes numbers |
-# for all opcodes. |
-# |
-# The lines of the vdbe.c that we are interested in are of the form: |
-# |
-# case OP_aaaa: /* same as TK_bbbbb */ |
-# |
-# The TK_ comment is optional. If it is present, then the value assigned to |
-# the OP_ is the same as the TK_ value. If missing, the OP_ value is assigned |
-# a small integer that is different from every other OP_ value. |
-# |
-# We go to the trouble of making some OP_ values the same as TK_ values |
-# as an optimization. During parsing, things like expression operators |
-# are coded with TK_ values such as TK_ADD, TK_DIVIDE, and so forth. Later |
-# during code generation, we need to generate corresponding opcodes like |
-# OP_Add and OP_Divide. By making TK_ADD==OP_Add and TK_DIVIDE==OP_Divide, |
-# code to translate from one to the other is avoided. This makes the |
-# code generator run (infinitesimally) faster and more importantly it makes |
-# the library footprint smaller. |
-# |
-# This script also scans for lines of the form: |
-# |
-# case OP_aaaa: /* jump, in1, in2, in3, out2-prerelease, out3 */ |
-# |
-# When such comments are found on an opcode, it means that certain |
-# properties apply to that opcode. Set corresponding flags using the |
-# OPFLG_INITIALIZER macro. |
