There were several reasons; 1) the proliferation of "non-standard" things that the GNU crowd calls 'features' in newer versions of the compiler -- some of which actually break 'standards compliant' code. 2) The proliferation of situations under which newer versions of the GCC compiler generate 'bad code' -- code that does *NOT* do what it is supposed to do. 3) The GPL, version *3* -- which applies to all newer versions of the GCC compiler -- is unacceptable to a large part of the FreeBSD community. Items 1) and 2) were ongoing nuisances. Item 3) all by itself, was the deal breaker. clang was selected over alternatives -- including keeping the 'old' (GPL v2) GCC, on the basis of: a) better standards compliance. b) *FAR* better error messages. c) guality of generated code. d) 'non-restrictive' licensing. The GPL V3 has been responsible for a lot of people, besides FreeBSD, going looking for alternatives to any GPL-licensed code. GNU is well on the way to 'radicalizing' itself out of significance. They would rather be ideologically pure than 'widely accepted'. It _is_ their right to do so, but it makes life 'difficult' for those who have interests in building profit-based products using their tools. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
