Hi Clem, I have in the past when you suggested it.
Since you’ve got direct access to that compiler at your finger tips, I’d be glad to hear about any simh build issues you may encounter from time to time. Thanks. - Mark From: Clem Cole [mailto:[email protected]] Sent: Friday, May 27, 2016 2:03 PM To: Mark Pizzolato <[email protected]> Cc: Kevin Handy <[email protected]>; [email protected] Subject: Re: [Simh] Compiler differences Is there a reasonable benchmark - moral equivalent of running the 741 op-amp thru spice - Say a VAX under BSDx or VMS running some defined load? Also have you ever tried the DEC^h^h^hIntel C compiler on an x86 or INTEL*64 target (Linux, Winders, or OS X).

If you’re only compiling a single simulator (which most users are probably interested in) the compile time difference isn’t enough to worry about. When changes to simulators are made, compiling with both gcc and clang are used since these compilers tend to detect different errors. - Mark From: Simh [mailto:[email protected]<javascript:_e(%7B%7D,'cvml','[email protected]');>] On Behalf Of Kevin Handy Sent: Friday, May 27, 2016 12:04 PM To: [email protected]<javascript:_e(%7B%7D,'cvml','[email protected]');> Subject: [Simh] Compiler differences Has anyone done a comparison (benchmarks) between simh emulators compiled with g++ verses clang? clang seems to me to run quite a bit faster than gcc, but I haven't run any actual comparisons between the two so it is completely subjective. A full 'make' seems to build faster with clang than gcc. Just curious. I recently noticed bthe clang stuff in the makefile, so I thought I'd try it out. -- Sent from a handheld expect more typos than usual
