* * generic/tclCompExpr.c: Call TclCompileSyntaxError() whendgp2007-08-275-189/+72
| | | | | | | | | | | | | | | | 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.

| | | | | overflow detection in sums, adapt to subtraction. Lenghty comment added.
* Swapped the order in the Overflowing macro (created in the last commit byMiguel Sofer2007-08-191-2/+5
| | | | Donal): check first the condition most likely to fail in its usage by [incr].
* Make Miguel's overflow-detection more mnemonic with a macro.dkf2007-08-191-73/+86

* * generic/tclExecute.c: changed the check for overflow in sums,Miguel Sofer2007-08-191-18/+12
| | | | | | | | | | | reducing objsize, number of branches and cache misses (according to cachegrind). Non-overflow for s=a+b: previous ((a >= 0 || b >= 0 || s < 0) && (s >= 0 || b < 0 || a < 0)) now (((a^s) >= 0) || ((a^b) < 0)) This expresses: "a and s have the same sign or else a and b have different sign".

* * generic/tclCompExpr.c: Added a "constant" field to the OpNodedgp2007-08-161-90/+296
| | | | | | | | 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 in [Bug 1564517].

| | | | | | | | | * generic/tclCompExpr.c: Added a "mark" field to the OpNode struct, which is used to guide tree traversal.
