Subject: [PATCH] libsanitizer: Remove cyclades from libsanitizer
|
|
The Linux kernel has removed the interface to cyclades from
|
the latest kernel headers[1] due to them being orphaned for the
|
past 13 years.
|
|
libsanitizer uses this header when compiling against glibc, but
|
glibcs itself doesn't seem to have any references to cyclades.
|
|
Further more it seems that the driver is broken in the kernel and
|
the firmware doesn't seem to be available anymore.
|
|
As such since this is breaking the build of libsanitizer (and so the
|
GCC bootstrap[2]) I propose to remove this.
