Hi, I am using m5thread. I come into a problem with compiling the m5thread. I
use a alpha cross-compiler. It gives the following errors:
alphaev67-unknown-linux-gnu-gcc -g -O3 -DM5_PROFILING -c ../pthread.c -o
../pthread.o
In file included from ../pthread.c:47:
../tls_defs.h:168:4: error: #error "No TLS defs for your architecture"
In file included from ../pthread.c:48:
../profiling_hooks.h:37:3: error: #error "M5 profiling hooks not implemented
for your architecture, write them"
make: *** [../pthread.o] Error 1
>From tls_defs.h, I see TLS support is only defined for architecture x86_64,
>amd64 and sparc.
>From profiling_hooks.h, I see profiling hooks is only defined for architecture
>sparc, Is anyone know how to define TLS support and profiling hooks for alpha?
>Thank you very much.
