expression syntax errors are found when compiling expressions. With
this in place, convert TclCompileExpr to return void, since there's no
longer any need to report TCL_ERROR.
* generic/tclCompile.c: Update callers.
* generic/tclExecute.c:
* generic/tclCompCmds.c: New routine TclCompileSyntaxError()
* generic/tclCompile.h: to directly compile bytecodes that report a
* generic/tclCompile.c: syntax error, rather than (ab)use a call to
TclCompileReturnCmd. Also, undo the most recent commit that papered
over some issues with that (ab)use. New routine produces a new
opcode INST_SYNTAX, which is a minor variation of INST_RETURN_IMM.
Also a bit of constification.

intreps when literals are created for the first time. Correct memleak

struct (again "free" due to alignment requirements) to mark those
subexpressions that are completely known at compile time. Enhanced
CompileExprTree() and its callers to precompute these constant
subexpressions at compile time. This resolves the issue raised

OpNode mark field scheme of tree traversal. This eliminates the need
to use magic values in the left and right fields for that purpose.
Also stop abusing the left field within ParseExpr() to store the
number of arguments in a parsed function call. CompileExprTree() now
determines that for itself at compile time.
|
|
|
|
|
|
|
|
|
| |
* generic/tclCompExpr.c: Added a "mark" field to the OpNode
struct, which is used to guide tree traversal. This field costs
nothing since alignement requirements used the memory already.
Rewrote ConvertTreeToTokens() to use the new field, which permitted
consolidation of utility routines CopyTokens() and
GenerateTokensForLiteral().

ParseExpr() to indicate whether the caller is Tcl_ParseExpr(), with an
end goal of filling a Tcl_Parse with Tcl_Tokens representing the
parsed expression, or TclCompileExpr() with the goal of compiling and
executing the expression. In the latter case, more aggressive
conversion of QUOTED and BRACED lexeme to literals is done. In the
former case, all such conversion is avoided, since Tcl_Token production
would revert it anyway. This enables simplifications to the
GenerateTokensForLiteral() routine as well.

to be stored directly in the parse tree. There's no memory cost to
this addition, since that memory would have been lost to alignment
issues anyway. Also, converted precedence definitions and lookup
tables to use symbolic constants instead of raw number for improved
readability, and continued extending/improving/correcting comments.
