[HP aCC 6.15] lots of noise due to compiler remarks
---------------------------------------------------
Key: STDCXX-695
URL: https://issues.apache.org/jira/browse/STDCXX-695
Project: C++ Standard Library
Issue Type: Bug
Components: Build
Affects Versions: 4.2.0
Environment: HP aCC 6.15
Reporter: Martin Sebor
The latest HP compiler on IPF issues lots of remarks, making our builds
exceedingly noisy.
Here's a breakdown of all the remarks we get in a recent 12S build along with
the number of each:
F=hpux-11.31-ia64-acc-6.15-12S-610576-log; \
R=`sed -n "s/.*: remark \(#[1-9][0-9]*-.\): .*/\1/p" $F | sort | uniq`; \
for r in $R; do \
n=`grep ": remark $r: " $F | wc -l`; echo $r: $n; \
done
#2177-D: 8 variable was declared but never referenced
#2181-D: 9 argument is incompatible with corresponding format string
conversion
#2550-D: 28 variable was set but never used
#2826-D: 44 parameter was never referenced
#2961-D: 1 use of a type with no linkage to declare a variable with linkage
#3235-D: 1 nonstandard conversion between pointer to function and pointer to
data
#3348-D: 799 declaration hides constant or variable
#4217-D: 3 comparison of enum (represented as an unsigned integer) with zero
#4219-D: 250 64 bit migration: type conversion may truncate value
#4234-D: 28 type conversion may lose significant bits
#4239-D: 2 case type mismatch with switch expression type
#4244-D: 4 extern storage class used with a function definition
#4248-D: 4 comparison of unsigned integer with a signed integer
#4271-D: 780 type conversion may lose sign
#4273-D: 18 floating-point equality and inequality comparisons may be
inappropriate due to roundoff common in floating-point computation
#4278-D: 3 the subexpression in logical expression is a constant
#4282-D: 34 virtual function is called from constructor/destructor
#4283-D: 3 access global variable in constructor
#4296-D: 695 arithmetic operation on boolean type
#4297-D: 1220 boolean value is used as array index
#4298-D: 124 64 bit migration: addition result could be truncated before cast
to bigger sized type
#4299-D: 20 64 bit migration: multiply result could be truncated before cast
to bigger sized type
#4300-D: 60 Overflow while computing constant in left shift operation
#4315-D: 60 while loop without body, did you insert an extra ';'?
