Use TLS initial-exec model for __libc_tsd_CTYPE_* thread variables [BZ #33234]
|
|
|
|
Commit 10a66a8e421b ("Remove <libc-tsd.h>") removed the TLS initial-exec
|
|
(IE) model attribute from the __libc_tsd_CTYPE_* thread variable declarations
|
|
and definitions. Commit a894f04d8776 ("Optimize __libc_tsd_* thread
|
|
variable access") restored it on declarations.
|
|
|
|
Restore the TLS initial-exec model attribute on __libc_tsd_CTYPE_* thread
|
|
variable definitions.
|
|
|
|
This resolves test tst-locale1 failure on s390 32-bit, when using a
|
|
GNU linker without the fix from GNU binutils commit aefebe82dc89
|
|
("IBM zSystems: Fix offset relative to static TLS").
