From 2b5174253155bdace1262ea2ab53d11347ecdefd Mon Sep 17 00:00:00 2001 From: Adhemerval Zanella Date: Tue, 31 Mar 2020 15:43:25 -0300 Subject: nptl: Move cancel state out of cancelhandling Now that thread cancellation state is not accessed concurrently anymore, it is possible to move it out the 'cancelhandling'. The code is also simplified: CANCELLATION_P is replaced with a internal pthread_testcancel call and the CANCELSTATE_BIT{MASK} is removed. With this behavior pthread_setcancelstate does not require to act on cancellation if cancel type is asynchronous (is already handled either by pthread_setcanceltype or by the signal handler). Checked on x86_64-linux-gnu and aarch64-linux-gnu. --- manual/process.texi | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) (limited to 'manual/process.texi') diff --git a/manual/process.texi b/manual/process.texi index 54e65f76c6..134d5c6143 100644 --- a/manual/process.texi +++ b/manual/process.texi @@ -68,7 +68,7 @@ until the subprogram terminates before you can do anything else. @c CLEANUP_HANDLER @ascuplugin @ascuheap @acsmem @c libc_cleanup_region_start @ascuplugin @ascuheap @acsmem @c pthread_cleanup_push_defer @ascuplugin @ascuheap @acsmem -@c CANCELLATION_P @ascuplugin @ascuheap @acsmem +@c __pthread_testcancel @ascuplugin @ascuheap @acsmem @c CANCEL_ENABLED_AND_CANCELED ok @c do_cancel @ascuplugin @ascuheap @acsmem @c cancel_handler ok @@ -86,7 +86,6 @@ until the subprogram terminates before you can do anything else. @c SINGLE_THREAD_P ok @c LIBC_CANCEL_ASYNC @ascuplugin @ascuheap @acsmem @c libc_enable_asynccancel @ascuplugin @ascuheap @acsmem -@c CANCEL_ENABLED_AND_CANCELED_AND_ASYNCHRONOUS dup ok @c do_cancel dup @ascuplugin @ascuheap @acsmem @c LIBC_CANCEL_RESET ok @c libc_disable_asynccancel ok -- cgit 1.4.1
