It's possible for this platform to put the Infinity macros before libthread_db's DB_THREAD_SELF, and define DB_THREAD_SELF in terms of the Infinity values, but I wasn't sure if it would be appropriate. --- sysdeps/alpha/nptl/tls.h | 6 ++++++ 1 files changed, 6 insertions(+), 0 deletions(-) diff --git a/sysdeps/alpha/nptl/tls.h b/sysdeps/alpha/nptl/tls.h index 4eddf40..77288e8 100644 --- a/sysdeps/alpha/nptl/tls.h +++ b/sysdeps/alpha/nptl/tls.h @@ -102,6 +102,12 @@ typedef struct # define DB_THREAD_SELF \ REGISTER (64, 64, 32 * 8, -sizeof (struct pthread)) +/* Magic for Infinity to know how to do THREAD_SELF. */ +# define I8_THREAD_SELF I8_TS_REGISTER +# define I8_TS_REG_SIZE 64 +# define I8_TS_REG_OFFSET 32 * 8 +# define I8_TS_REG_BIAS -sizeof (struct pthread) + /* Access to data in the thread descriptor is easy. */ #define THREAD_GETMEM(descr, member) \ descr->member
