From: "john at atrove dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug java/13021] New: GCJ Boehm descriptor may be incorrect if alignment != sizeof(void*) Date: Wed, 12 Nov 2003 12:25:00 -0000 [thread overview] Message-ID: <20031112122506.13021.john@atrove.com> (raw) The boehm descriptor generated by GCJ may be incorrect if the alignment is not the same as the sizeof(void*). This is the case with the m68k, where the aligment is 16 bits, whilst a void* takes 32 bits. The problem is that the boehm calualation truncates the descriptor, causing the boehm garbage collector to miss pointers, if a bitmap descriptor is generated and all pointers are not aligned to sizeof(void*). If all the fields are not aligned to sizeof(void*), then a procedure descriptor should be generated. -- Summary: GCJ Boehm descriptor may be incorrect if alignment != sizeof(void*) Product: gcc Version: 3.4 Status: UNCONFIRMED Severity: normal Priority: P2 Component: java AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: john at atrove dot com CC: gcc-bugs at gcc dot gnu dot org GCC host triplet: i686-pc-cygwin GCC target triplet: m68k-unknown-coff http://gcc.gnu.org/bugzilla/show_bug.cgi?id=13021
