Bug ID: 86294
Summary: comparison is always true due to limited range of data
type [-Werror=type-limits]
Product: gcc
Version: 9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libitm
Assignee: unassigned at gcc dot gnu.org
Reporter: um at mutluit dot com
Target Milestone: ---
If warnings are treated as error (I think that's the default, or gets
implicitly activated if -Wall -Wextra has been given), then if
-Wno-error=type-limits has not been defined, then the following error gets
reported and the build aborts:
../../../gcc_trunk/libitm/method-ml.cc: In member function 'virtual bool
{anonymous}::ml_wt_dispatch::supports(unsigned int)':
../../../gcc_trunk/libitm/method-ml.cc:650:35: error: comparison is always true
due to limited range of data type [-Werror=type-limits]
return (number_of_threads * 2 <= ml_mg::OVERFLOW_RESERVE);
