             Bug #: 15223
           Summary: reversed order of inlined function parameters
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: symtab
        AssignedTo: unassigned@sourceware.org
        ReportedBy: jan.kratochvil@redhat.com
    Classification: Unclassified
            Target: x86_64-unknown-linux-gnu


--------------------------------------------------------------------------------
int v;
__attribute__((always_inline)) static void
f (int a, int b, int c)
{
  v = a + b + c;
}
int
main (void)
{
  f (1, 2, 3);
  return 0;
}
--------------------------------------------------------------------------------
gcc -Wall -g 
(it occurs also with -O2 and without explicit always_inline)
--------------------------------------------------------------------------------
OK:
 <1><2d>: Abbrev Number: 2 (DW_TAG_subprogram)7
    <2e>   DW_AT_name        : f        
 <2><38>: Abbrev Number: 3 (DW_TAG_formal_parameter)
    <39>   DW_AT_name        : a        
 <2><41>: Abbrev Number: 3 (DW_TAG_formal_parameter)
    <42>   DW_AT_name        : b        
but the instance has them in reversed order:
 <2><81>: Abbrev Number: 6 (DW_TAG_inlined_subroutine)
    <82>   DW_AT_abstract_origin: <0x2d>        
    <86>   DW_AT_low_pc      : 0x40046d 
    <8e>   DW_AT_high_pc     : 0x40047e 
 <3><a0>: Abbrev Number: 7 (DW_TAG_formal_parameter)
    <a1>   DW_AT_abstract_origin: <0x41>        
    <a5>   DW_AT_location    : 2 byte block: 91 68      (DW_OP_fbreg: -24)
 <3><a8>: Abbrev Number: 7 (DW_TAG_formal_parameter)
    <a9>   DW_AT_abstract_origin: <0x38>        
    <ad>   DW_AT_location    : 2 byte block: 91 6c      (DW_OP_fbreg: -20)
--------------------------------------------------------------------------------
GDB output is reversed then:
f (c=3, b=2, a=1) at 16.c:5
