Hi I am looking at the RTEMS x86 TLS support. When -fPIC is specified, gcc generates calls to ___tls_get_addr(). But when it is not specified, there are no external calls. To make sure we are doing the right thing, I have a few questions:
+ What is expected for "get TLS" when __tls_get_addr() is not called? + Can we force all RTEMS i386 gcc configurations to make the function call to __tls_get_addr()? We have an implementation of it for ARM so it would be the same. So this would be a simple solution for us. + Is there any reference material to show what is expected for each architecture? I think the MIPS generates an illegal instruction and you end up doing TLS in there. It would be easier if we could configure gcc to make subroutine calls to __tls_get_addr() instead generically? Anything else about TLS and run-time requirements we should know? -- Joel Sherrill, Ph.D. Director of Research & Development joel.sherr...@oarcorp.com On-Line Applications Research Ask me about RTEMS: a free RTOS Huntsville AL 35806 Support Available (256) 722-9985
