Fix Wvarargs warning in XFA error code.chromium/2722chromium/2721chromium/2719chromium/2718
Chrome has enabled the -Wvarargs warning that was added to clang, this fails
with PDFium XFA builds due to two warnings:
../../xfa/fxfa/fm2js/xfa_lexer.cpp:539:16: error: passing an object that
undergoes default argument promotion to 'va_start' has undefined behavior
[-Werror,-Wvarargs]
va_start(ap, msg);
^
../../xfa/fxfa/fm2js/xfa_lexer.cpp:535:40: note: parameter of type
'XFA_FM_ERRMSG' is declared here
void CXFA_FMLexer::Error(XFA_FM_ERRMSG msg, ...) {
The issue is that XFA_FM_ERRMSG is an enum and we violate the promotion rules
for passing the value to va_start.
I removed the enum and named the flags explicitly then pass in the string as
the argument.
