From scripts/compile pushed default assumption of #:from as 'scheme down
into system/base/compile where filename and first line can be used to
deduce intended "from" language. If first line of a file is of the form
#lang ecmascript
then the file is assumed consist of source language "ecmascript".
* module/scripts/compile.scm (compile): changed default #:from to #f
from 'scheme
* module/system/base/compile.scm(lang-from-port, %file-extension-map,
add-lang-extension, lang-extension-for): added global
%file-extension-map with accessor lang-extension-for and updater
add-lang-extension. Also, added lang-from-port to parse first line,
looking for #lang.
* test-suite/tests.scm: added "load-lang" test.
* test-suite/Makefile.am(SCM_TESTS): added tests/load-lang.test
Locations are stored in tree-il records in "source vector" form, but
`location-string' was rendering these as <unknown-location>.
* module/system/base/message.scm (location-string): Support locations
passed as a file/line/column vector.
NetBSD and pkgsrc have been using an empty vendor string since the
mid-'90s, such as x86_64--netbsd. pkgsrc has been carrying around a
workaround just the guile build for a long time. (Before that,
NetBSD omitted the vendor altogether, so if x86_64 existed then it
might have been `x86_64-netbsd', but that caused more problems.)
This change makes Guile accept an empty vendor string so workarounds
are no longer necessary.
* module/system/base/target.scm (validate-target): Allow empty vendor
string in GNU target triplets.
* test-suite/tests/cross-compilation.test ("cross-compilation"): Add
tests for "x86_64--netbsd".
