From a6b3657be6bc5067aeec98d990f60765361c6557 Mon Sep 17 00:00:00 2001 From: Richard Henderson Date: Wed, 21 May 2014 11:36:51 -0400 Subject: aarch64: Merge __local_multiple_threads offset with memory reference This also highlights that we'd been loading 64-bits instead of the proper 32-bits. Caught by the linker as a relocation error, since the variable happened to be unaligned for 64-bits. --- sysdeps/unix/sysv/linux/aarch64/nptl/sysdep-cancel.h | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-) (limited to 'sysdeps/unix/sysv/linux') diff --git a/sysdeps/unix/sysv/linux/aarch64/nptl/sysdep-cancel.h b/sysdeps/unix/sysv/linux/aarch64/nptl/sysdep-cancel.h index 0e9bef3..24fae7b 100644 --- a/sysdeps/unix/sysv/linux/aarch64/nptl/sysdep-cancel.h +++ b/sysdeps/unix/sysv/linux/aarch64/nptl/sysdep-cancel.h @@ -163,9 +163,8 @@ extern int __local_multiple_threads attribute_hidden; # else # define SINGLE_THREAD_P \ adrp x16, __local_multiple_threads; \ - add x16, x16, #:lo12:__local_multiple_threads; \ - ldr x16, [x16]; \ - cmp x16, 0; + ldr w16, [x16, :lo12:__local_multiple_threads]; \ + cmp w16, 0; # endif # else /* There is no __local_multiple_threads for librt, so use the TCB. */ @@ -181,12 +180,12 @@ extern int __local_multiple_threads attribute_hidden; cfi_rel_offset (x30, 8); \ bl __read_tp; \ sub x0, x0, PTHREAD_SIZEOF; \ - ldr x16, [x0, PTHREAD_MULTIPLE_THREADS_OFFSET]; \ + ldr w16, [x0, PTHREAD_MULTIPLE_THREADS_OFFSET]; \ ldp x0, x30, [sp], 16; \ cfi_restore (x0); \ cfi_restore (x30); \ cfi_adjust_cfa_offset (-16); \ - cmp x16, 0 + cmp w16, 0 # define SINGLE_THREAD_P_PIC(x) SINGLE_THREAD_P # endif # endif -- cgit v1.1
