Thank you Paul,
Now even after I put the cr_arch.h and cr_atomic.h under
libcr/arch/sparc, the following errors appear:
In file included from ../../libcr/cr_async.c:37:
../../libcr/cr_private.h:63:23: error: cr_atomic.h: No such file or directory
In file included from ../../libcr/cr_private.h:65,
from ../../libcr/cr_async.c:37:
[some more errors]
../../libcr/cr_private.h:66:21: error: cr_arch.h: No such file or directory
Do I have to change something else for blcr to realize the files' existence?
Also, would you be able to point me to some other resources for the
assembly codes? For cr_atomic.h, I understood how to implement
compare_and_swap but I am not able to infer the atomic increment and
decrement and test from the glibc source codes as well as the source
for other architectures. For the syscall functions, would you know of
where can I look into? Should the glibc have these?
Thank you very much for the help, I've been slowly looking into these
for a while, but my inexperience hinders me from advancing as quick.
