From: Piotr Trojanek Date: Mon, 11 Jun 2018 09:17:56 +0000 (+0000) Subject: [Ada] Don't split AND THEN expressions in GNATprove_Mode X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=270c6b4d6f9300f36cb7e06594d71a62ab59af0a;p=gcc.git [Ada] Don't split AND THEN expressions in GNATprove_Mode Splitting AND THEN expressions in contracts into separate pragma Check is only useful for compilation when the error message points to a failed conjunct. For proof it is of no use; for flow analysis it is annoying. Also, it makes debugging harder. Now it is disabled in GNATprove_Mode. Compilation is not affected, so no test provided. 2018-06-11 Piotr Trojanek gcc/ada/ * sem_ch13.adb (Analyze_Aspect_Specifications): Don't split AND THEN expressions in Pre/Post contracts while in GNATprove_Mode.
