Description Joseph S. Myers 2005-12-20 21:31:23 UTC
MULTILIB_OSDIRNAMES, as used in target makefile fragments t-*, is undocumented.
Comment 1 Andrew Pinski 2005-12-25 01:03:40 UTC
Comment 2 Eric Gallager 2014-12-22 22:03:15 UTC
In some of the t-linux64 Makefile fragments in config/gcc/, I found the following comment that seems to describe what the value of MULTILIB_OSDIRNAMES represents: # On Debian, Ubuntu and other derivative distributions, the 32bit libraries # are found in /lib32 and /usr/lib32, /lib64 and /usr/lib64 are symlinks to # /lib and /usr/lib, while other distributions install libraries into /lib64 # and /usr/lib64. The LSB does not enforce the use of /lib64 and /usr/lib64, # it doesn't tell anything about the 32bit libraries on those systems. Set # MULTILIB_OSDIRNAMES according to what is found on the target. Is there a more central location to which this comment should be moved? Or should it just be copied-and-pasted to the rest of the 64bit-Linux-specific Makefile fragments as well?

The point isn't documenting the rationale for particular choices, it's documenting (in fragments.texi) the general semantics, including for the A=B and A=!B forms. It looks like the documentation was added by r193508 | doko | 2012-11-14 21:29:15 +0000 (Wed, 14 Nov 2012) | 36 lines but without closing this bug.
