GCC complains that inlining virStringTrimOptionalNewline is not likely on some platforms: cc1: warnings being treated as errors ../../src/util/virfile.c: In function 'virFileReadValueBitmap': ../../src/util/virstring.h:292: error: inlining failed in call to 'virStringTrimOptionalNewline': call is unlikely and code size would grow [-Winline] ../../src/util/virfile.c:3987: error: called from here [-Winline] Inlining this function is not going to be a measurable performance benefit either, since the time required to execute it is going to be dominated by running of strlen() over the string, not by the function call overhead.
