* * generic/tclCompExpr.c: Call TclCompileSyntaxError() whendgp2007-08-271-69/+11
| | | | | | | | | | | | | | | | 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.

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/tclExecute.c (TEBC, TclGetSrcInfoForCmd): * generic/tclInt.h: * generic/tclTrace.c (TclCheck(Interp|Execution)Traces): Removed the need for TEBC to inspect the command before calling TEOvI, leveraging the TIP 282 infrastructure.

TclStackFree now takes a (void *) argument which is the pointer intended to be freed. TclStackFree will panic if that's not actually the memory the call will free.

These tests expose a change in dynamics due to a recent round of optimisations. The "correct" behaviour is not described in docs nor TIP 62.
