exp_ch4.adb (Expand_Concatenate): Remove wrapping in expression-with-actions node.

[gcc.git] / gcc / ada / ChangeLog

2013-04-11  Robert Dewar  <dewar@adacore.com>

        * exp_ch4.adb (Expand_Concatenate): Remove wrapping in
        expression-with-actions node. No longer needed given fix to
        sem_prag and caused loss of some useful warnings.
        * sem.ads: Minor reformatting.
        * sem_prag.adb (Check_Disabled): Removed, to be replaced by not
        Check_Enabled. These two routines were curiously incompatible
        causing confusion.
        (Analyze_Pragma, case Check): Make sure we do
        not expand the string argument if the check is disabled. Avoid
        use of Check_Disabled, which resulted in missing analysis in
        some cases.
        * sem_prag.ads (Check_Disabled): Removed, to be replaced by not
        Check_Enabled. These two routines were curiously incompatible
        causing confusion.

2013-04-11  Hristian Kirtchev  <kirtchev@adacore.com>

        * exp_ch4.adb (Process_Transient_Object): Use
        an unchecked conversion when associating a transient controlled
        object with its "hook".

2013-04-11  Ed Schonberg  <schonberg@adacore.com>

        * sem_prag.adb (Analyze_Pragma, case
        Preelaborable_Initialization): The pragma is legal if it comes
        from an aspect on the private view of the type, even though its
        analysis point takes place later at the freeze point.

2013-04-11  Robert Dewar  <dewar@adacore.com>

        * sem_ch6.adb: Minor reformatting.
