Does anyone have any experience compiling the System III PDP-11 compilier to run on a VAX in other than PDP-11 emulation mode. We are currently developing C programs on a VAX 11/750 for an PDP-11/23 running System III. We run the PDP-11 complier on the 11/750 by putting the 11/750 in PDP-11 emulation mode using the "compat" program. Using this scheme compilies seem to take a very long time so I just tried to compile the PDP-11 compilier wth the VAX compilier hoping that the PDP-11 compilier would running faster on the VAX if it was able to use the full VAX instruction set. The problem is that part of pass one, c1, is in PDP-11 assembly code. (The module is table.s). I would appreciate any answers to the following two questions. 1) Will the PDP-11 C compilier run faster if it is compiled under the native VAX compilier? 2) Has anyone converted the equivalent of "table.i" to either C code or VAX assembly code?
