asmHighlighter Works With JWASM!

I used asmHighlighter 1.3 with MASM versions 8, 9 & 10 and the advanced SSE instructions do not highlight or assemble within Visual Studio 2005, 2008 or 2010, but I am thrilled to say that JWASM version 2.02, released 01/19/2010, while it also doesn't highlight all the SSE instructions, it does assemble all the instructions through SSE 4.2! Yeah! JWASM is an excellent direct replacement for MASM. I directly replaced MASM v9 from Visual Studio 2008 with JWASM 2.02 by simply installing JWASM and changing the Visual Studio Custom Build Rules to use JASM and not MASM, changing the project setting of JWASM to use the include directories I was using with MASM, and everything assembled perfectly, and this was for an embedded avionics package that is no lightweight product. This took only 15 minutes. I then installed asmHighlighter 1.3, crossed my fingers, and re-built all the projects. It worked! No failure to assemble the SSE 4.2 instructions as with MASM! The highlighting worked, outside of those few SSE instructions that don't highlight yet, but no failures to build. This is huge for me as I really love the highlighting asmHighlighter does for assembly language files, but with MASM I had to uninstall asmHighlighter as MASM wouldn't assemble the latest SSE instructions with it installed. MASM fails to assemble all SSE instruction but JWASM does not. I highly recommend both JWASM 2.02 and asmHighlighter 1.3 as a fantastic combination for assembly language programming within Visual Studio. Did I mention I was thrilled?! I'll post this on the JWASM board as well.

Thanks for your report, glad to see that AsmHighlighter is used! ;) I don't remember, but the highlight for SSE 4.2 is probably not integrated in AsmHighlighter... and I don't think It's part of Masm either (and there is no reason that masm and asmhighlighter should interfere, weird bug you had)...

It was a wierd bug, but, then again, MASM seems to be fragile and does many unexpected things. I've been using MASM for over 20 years and have learned to overcome its bugs. I was really happy to see the structure alignment bug fixed in JWASM, so much so that I have moved all devlopement to it. JWASM was able to build a highly complex and large set of projects without any failure in the thousands of tests involved in the product. I am sure there might be a bug in JWASM somewhere, but nothing like MASM so far.  Having the Asmhighlighter work was great as the one developed in house had little support and we have no time to build one. I really like to see comments in green. :)
