2015-02-15Do not generate code dereferencing type-punned pointersJustus Winter
For variable-length arrays, up to 2048 bytes are transmitted inline. If the array is larger, the data is transmitted out-of-line, and a pointer to a vm_allocated region is stored at the beginning of the array. Previously, the generated code casted the field. Use a union instead. This fixes the gcc warning `dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]'. * global.c (OOLPostfix): New variable. * global.h (OOLPostfix): New declaration. * server.c (WriteServerCallArg): Avoid cast. (WriteDestroyArg): Likewise. (WritePackArgValue): Likewise. (WritePackArg): Likewise. * user.c (WriteExtractArgValue): Likewise. * utils.c (WriteFieldDeclPrim): Generate a union with an additional pointer field for variable-length arrays.
2015-02-06Test the configured yacc programDavid Michael

2015-02-06Check that yacc is provided by bisonYves-Gael Cheny ( irc hurdman_begin )
* configure.ac: Check that yacc --version contains bison.
2014-12-01Add static branch prediction to type checksJustus Winter
Annotate generated type checks with static branch prediction optimizing well-formed messages. * utils.c (WriteBogusDefines): Define `mig_unlikely' if not defined. * server.c: Use `mig_unlikely' in generated type checks. * user.c: Likewise.
2014-11-06Provide default implementations for server functionsJustus Winter
By providing default implementations, servers can provide partial implementations of protocols without having to stub out functions. * server.c (WriteDefaultRoutine): New function. (WriteRoutine): Call WriteDefaultRoutine.
2014-10-10Add support for protected payloadsJustus Winter
Add support for protected payloads. The new `intranpayload' option can be used to specify a translation function translating payloads to values of the translated type. This function will be used instead of the `intran' function to to look up the receiving object of a message in a server. This makes it easy to use the protected payloads introduced in GNU Mach 1.5. An inTransPayload function translates payloads to objects, like an inTrans function translates from port names to objects. Generate code in the server routine to optimize lookups to the receiver of the message. Additionally, if no intran function is provided, but an intranpayload function is, it is expected to translate from payloads to port names. This is used to preserve the semantics in case the server routine expects a port name. * NEWS: Add item. * lexxer.l: Emit syInTranPayload. * parser.h: Define syInTranPayload. * parser.y (TransTypeSpec): Handle syInTranPayload. * type.h (struct ipc_type): Add itInTransPayload. * server.c (WriteExtractArgValue): If a payload-aware intrans function has been specified, use it to get a reference to the receiving object. * routine.c (rtAugmentArgKind): Force the use of a local variable if a payload-aware translate-in function is defined.

2014-02-21Fix variable-sized c stringsJustus Winter
Previously, the terminating zero of variable-sized c strings was only included when copying the message if the length of the string was not a multiple of four. mig_strncpy returns the length of the string excluding the terminating zero. Fix this by properly accounting for the byte for the terminating zero in the array length. * server.c (WritePackArgValue): Account for the terminating zero in the array length. * user.c (WritePackArgValue): Likewise.
2013-12-16Generate a x_server_routine in the sheader so it can be inlinedJustus Winter
* header.c (WriteServerHeader): Emit a x_server_routine that can be inlined. * server.c (WriteEpilog): Export the x_routines array so it can be used from the inlined x_server_routine.

2013-12-15mig/server.c (WriteVarDecls): quiet GCC warning about set but unused variableMarin Ramesa
This is again that code where variable is assigned to itself, but I don't know how to fix this the other way. * server.c (WriteVarDecls) (msgh_simple): Assign to itself.

2013-09-04Drop the auto keywordJustus Winter
Drop the auto keyword from the generated source code. auto is the default storage type for variables anyway and it is customary to omit it. * utils.c (WriteCheckDecl): Drop auto from generated source. (WriteStaticLongDecl): Likewise. (WriteStaticShortDecl): Likewise.
2013-08-19Drop alloca.cJustus Winter
