Handle ‘i386-nova’ as shorthand for a 4-part system name, kernel=rtmk os=nova, instead of a canonicalized OS name with a dash in the middle, os=rtmk-nova.
RTMK <https://rtmk.sourceforge.net/> is a microkernel. Nova <https://www.nongnu.org/nova> is an OS written on top of that microkernel. The short system name ‘i386-nova’ was therefore defined to canonicalize to ‘i386-pc-rtmk-nova’, I think prior to the general introduction of 4-part system names. ‘i386-pc-rtmk-nova’ still makes sense under the rules for interpreting 4-part names, but nowadays the logic for validating canonicalized name components rejects OS names with a dash in the middle. Feeding kernel=rtmk os=nova to that logic, instead, does the Right Thing. --- config.sub | 6 +++++- testsuite/config-sub.data | 1 + 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/config.sub b/config.sub index 9305b40..0eac68e 100755 --- a/config.sub +++ b/config.sub @@ -1632,7 +1632,8 @@ case $os in os=sysv ;; nova*) - os=rtmk-nova + kernel=rtmk + os=nova ;; # Preserve the version number of sinix5. sinix5.*) @@ -2015,6 +2016,7 @@ case $os in | nextstep* \ | nindy* \ | nonstopux* \ + | nova* \ | nsk* \ | nucleus* \ | nx6 \ @@ -2194,6 +2196,8 @@ case $kernel-$os-$obj in ;; os2-emx-) ;; + rtmk-nova-) + ;; *-eabi*- | *-gnueabi*-) ;; none--*) diff --git a/testsuite/config-sub.data b/testsuite/config-sub.data index 568778d..17e3790 100644 --- a/testsuite/config-sub.data +++ b/testsuite/config-sub.data @@ -328,6 +328,7 @@ i386-mingw32 i386-pc-mingw32 i386-msys i386-pc-msys i386-netbsd i386-pc-netbsd i386-next-openstep4 i386-next-openstep4 +i386-nova i386-pc-rtmk-nova i386-openbsd i386-pc-openbsd i386-os2 i386-pc-os2 i386-pc-nacl i386-pc-nacl -- 2.43.2
