Hello,

when using current GCC mainline and a function gets inlined
(by -funit-at-a-time)
GDB can't show variables of inlined function
(No symbol "incoming" in current context.)

The relevant part of debug info:

without inlining:

        .uleb128 0x25   # (DIE (0x458a) DW_TAG_variable)
        .long   .LASF986        # DW_AT_name: "incoming"
        .byte   0x1     # DW_AT_decl_file
        .value  0x3f32  # DW_AT_decl_line
        .long   0x2d    # DW_AT_type
        .byte   0x1     # DW_AT_location
        .byte   0x55    # DW_OP_reg5

with inlining:

        .uleb128 0x2c   # (DIE (0x2a5a) DW_TAG_variable)
        .long   0x2af2  # DW_AT_abstract_origin
                ^^^^^^
        .byte   0x1     # DW_AT_location
        .byte   0x56    # DW_OP_reg6
...
        .long   0x2d    # DW_AT_type
        .uleb128 0x24   # (DIE (0x2af2) DW_TAG_variable)
                                ^^^^^^
        .long   .LASF850        # DW_AT_name: "incoming"
        .byte   0x1     # DW_AT_decl_file
        .value  0x3f32  # DW_AT_decl_line
        .long   0x2d    # DW_AT_type

The location seems not to be generated for the real variable record
(2nd part after ...) with inlining.

Should GCC generate the location for the second part (after ...) too,
should GDB be able to link the descriptions through the marked number
or something else?

Thanks.

Josef
