[fpc-devel] Odd test failure on x86_64-win64

[Pierre Muller]

Please look at:


https://www.freepascal.org/testsuite/cgi-bin/new-testsuite2.cgi?action=4&testfileid=5630

.rdata support, i.e. read-only data sections,
is not supported in several CPU-OS combination,
and  IIRC, it is even worse for PIC code,
but I don't really know if these special limitations
should not be removed...

See TGNUAssembler.sectionname method in compiler/aggas.pas unit,
and difference between secnames and secnames_pic inside that method.
