Subject: [Ada] Disable Support_Atomic_Primitives on QNX and VxWorks targets
Date: Mon, 12 Sep 2022 10:19:14 +0200 [thread overview]
Message-ID: <20220912081914.GA1512783@poulhies-Precision-5550> (raw)
[-- Attachment #1: Type: text/plain, Size: 524 bytes --]
The current configuration of the QNX and VxWorks runtimes does not support
atomic primitives.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* libgnat/system-qnx-arm.ads: Set Support_Atomic_Primitives to
false.
* libgnat/system-vxworks7-aarch64.ads: Ditto.
* libgnat/system-vxworks7-aarch64-rtp-smp.ads: Ditto.
* libgnat/system-vxworks7-arm.ads: Ditto.
* libgnat/system-vxworks7-arm-rtp-smp.ads: Ditto.
* libgnat/system-vxworks7-x86-kernel.ads: Ditto.
* libgnat/system-vxworks7-x86-rtp-smp.ads: Ditto.
