*	Fix -Os gnu_dev_* linknamespace, localplt issues (bug 15105, bug 19463).	Joseph Myers	2018-02-07	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Building with -Os produces linknamespace and localplt failures for, among other functions, gnu_dev_major, gnu_dev_minor and gnu_dev_makedev. The issue is that those functions are not inlined when building with -Os. While one could force them to be inlined in that case, it seems more natural to fix this issue similarly to other namespace issues. Thus, this patch makes gnu_dev_* into weak aliases for hidden symbols __gnu_dev_; __gnu_dev_ are then defined as inlines in the internal include/sys/sysmacros.h, and uses of gnu_dev_* (often via the macros major, minor and makedev) for which there are namespace issues are changed to use __gnu_dev_; where there are no namespace issues, use of libc_hidden_proto serves to avoid unnecessary local PLT entry use. Tested for x86_64, (a) without -Os, to verify the testsuite continues to pass without problems and that the functions called under their new names continue to be inlined as expected in that case; (b) with -Os, to verify that the linknamespace and localplt failures in question go away (but because of other such failures present, neither of the relevant bugs can yet be closed).
