the loader tries to access ld.so.nohwcap before loading any library

[Kyle Smith]

Binary package hint: libc6

Any time a library is loaded the loader tries to access /etc/ld.so.nohwcap before opening the library. Shouldn't this result be cached instead of doing it potentially hundreds of times? Or is this a side effect of using strace?

Steps to reproduce: strace any executable and the log should have plenty of entries lke this (assuming ld.so.nohwcap exists, otherwise it returns ENOENT):

access("/etc/ld.so.nohwcap", F_OK) = 0
open("/lib/libc.so.6", O_RDONLY) = 3
...

Nope, it's documented at the bottom of the ld.so manpage.

I just came across this after stracing a program I wrote and wondering where all these calls were coming from. I feel like excising that code from ld.so actually ;p

not a bug
