| H A D | locore.s | diff 90132 Sun Feb 03 07:13:58 MST 2002 bde Use osigreturn(2) instead of sigreturn(2) plus broken magic for returning from old signal handlers. This is simpler and faster, and fixes (new) sigreturn(2) when %eip in the new signal context happens to match the magic value (0x1d516). 0x1d516 is below the default ELF text section, so this probably never broken anything in practice. locore.s: In addition, don't build the signal trampoline for old signal handlers when it is not used. alpha: Not fixed, but seems to be even less broken in practice due to more advanced magic. A false match occurs for register #32 in mc_regs[]. Since there is no hardware register #32, a false match is only possible for direct calls to sigreturn(2) that happen to have the magic number in the spare mc_regs[32] field. |
