This bugfix is for a an ICE which occurs if an incompatible parameter is passed to a procedure. In particular if a REAL constant actual parameter is passed to INTEGER formal parameter then M2Range is invoked to check the type and then M2Range is called to check the value range. The value range check causes an ICE. The bug fix introduces range dependencies on type checks. If the type check fails an error message is generated and any future range check cancelled. These range and type checks are tightly coupled when generating parameter quad intermediate code. gcc/m2/ChangeLog: PR modula2/118978 * gm2-compiler/M2Check.mod (checkConstMeta): Add check for typed constants. * gm2-compiler/M2Quads.mod (BoolFrame): New field RangeDep. (CheckProcedureParameters): Call PutRangeDep to associate the range dependency with the parameter on the quad stack. Pass ParamCheckId to CheckParameter. (CheckProcTypeAndProcedure): Add ParamCheckId parameter. Pass ParamCheckId to BuildRange. (CheckParameter): New parameter ParamCheckId. Pass ParamCheckId to CheckProcTypeAndProcedure. (CheckParameterOrdinals): Add extra range dep parameter to the call of InitParameterRangeCheck. (ConvertBooleanToVariable): Initialize RangeDep field. (PushBacktok): Ditto.

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs.
