             Bug #: 55514

           Summary: PowerPC EABI: Warning: setting incorrect section

                    attributes for .sdata2

    Classification: Unclassified

           Product: gcc

           Version: 4.7.2

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: target

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: rdiezmail-...@yahoo.de





I am compiling with -meabi -msdata=eabi, and I am getting this compilation

warning every now and then:



  Warning: setting incorrect section attributes for .sdata2



This line of code triggers it:



  const uint8_t utf8TestStringKanji[] = { 0xE6, 0xBC, 0xA2, 0xE5, 0xAD, 0x97,

0x00 };



This is the assembler output for those 7 bytes of data:



 11768                      .section    .sdata2,"aw",@progbits

 11769                      .align 2

 11770                  .LC1:

 11771 0000 E6               .byte    -26

 11772 0001 BC               .byte    -68

 11773 0002 A2               .byte    -94

 11774 0003 E5               .byte    -27

 11775 0004 AD               .byte    -83

 11776 0005 97               .byte    -105

 11777 0006 00               .byte    0



The 'w' in the "aw" means "writable", which is wrong in this case.



I replaced that line of code with the following, which is more or less the same

for my purposes:



  const char * const utf8TestStringKanji = "\xE6\xBC\xA2\xE5\xAD\x97\x00";



And that compiles fine (no warnings).
