[Bug ld/13402] New: using "-Wl,--relax" on the AVR port causes lss file and debug information to "lose sync" with generated code
http://sourceware.org/bugzilla/show_bug.cgi?id=13402 Bug #: 13402 Summary: using "-Wl,--relax" on the AVR port causes lss file and debug information to "lose sync" with generated code Product: binutils Version: 2.20 Status: NEW Severity: normal Priority: P2 Component: ld AssignedTo: unassig...@sourceware.org ReportedBy: ilya.lesok...@gmail.com Classification: Unclassified When using "-Wl,--relax" on the AVR port and the size of an instruction actually changes, the location of the following instruction is not updated, So the lss file and debug information "lose sync" with the actual code. For example - the following code: .global main main: call a call b call c a: b: c: when compiled and relaxed generates an lss file with the following: ... 0092 : .global main main: call a 92:02 d0 rcall.+4 ; 0x98 <_exit> 94:01 d0 rcall.+2 ; 0x98 <_exit> call b 96:00 d0 rcall.+0 ; 0x98 <_exit> ... As can be seen call b is now pointing to what was originally call c, and call c is omitted. This makes debugging (in AVRStudio and probably other IDE's) of relaxed code difficult since the line's in the IDE dont match the line in the actual code. Also, it seems the code generated by gcc is not effected by this issue. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are on the CC list for the bug. ___ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
