Subject: * sysdeps/generic/libc-tls.c (__libc_setup_tls): Don't check for
X-Git-Tag: cvs/glibc-2-3~321
X-Git-Url: https://sourceware.org/git/?a=commitdiff_plain;h=d10c64301e56bd9cb77f5f480ba62df683ddbc5f;p=glibc.git

* sysdeps/generic/libc-tls.c (__libc_setup_tls): Don't check for

	PT_LOAD program headers and don't try to relocate PT_TLS's p_vaddr;
	it is already absolute.

	* elf/Makefile (tests): List tst-tls1 and tst-tls2 unconditionally.
	[$(build-static) = yes] (tests): Add tst-tls1-static, tst-tls2-static.
	[$(build-static) = yes] (tests-static): New variable.
	($(tests-static):%=$(objfpx)%.o)): New static pattern rule.
