[oi-dev] Recent /dev a9 repository ?

[Udo Grabowski (IMK)]

What I see now when disassembling the two products (e.g.,
/kernel/drv/adm64/mpt_sas), there are subtle style differences
in code arrangement:

mptsas_iport_attach()
     mptsas_iport_attach:       55                 pushq  %rbp
     mptsas_iport_attach+0x1:   48 8b ec           movq   %rsp,%rbp
     mptsas_iport_attach+0x4:   48 83 ec 10   **   subq   $0x10,%rsp
     mptsas_iport_attach+0x8:   48 89 7d f8        movq   %rdi,-0x8(%rbp)
     mptsas_iport_attach+0xc:   48 89 75 f0        movq   %rsi,-0x10(%rbp)

mptsas_iport_attach()
     mptsas_iport_attach:       55                 pushq  %rbp
     mptsas_iport_attach+0x1:   48 8b ec           movq   %rsp,%rbp
     mptsas_iport_attach+0x4:   48 89 7c 24 f8     movq   %rdi,-0x8(%rsp)
     mptsas_iport_attach+0x9:   48 89 74 24 f0     movq   %rsi,-0x10(%rsp)
     mptsas_iport_attach+0xe:   48 83 ec 10   **   subq   $0x10,%rsp

 From this I conclude that the oi_151a9 /dev/ official product is
produced with a different Sun CC version than the one mentioned in
the illumos build instructions. I have

cc: Sun C 5.9 SunOS_i386 Patch 124868-10 2009/04/30

reconstructed from a vanilla 12.0 compiler and the patches
124868-10  126496-03  126498-02

as well as the 12.1u1 lint checker
lint: Sun C 5.10 SunOS_i386 Patch 142363-03 2009/12/03

constructed from vanilla 12.1u1 with patches
141858-03  142363-03

Which one is the compiler oi_141a9 /dev is compiled with ?
And, if different, is it approved to do The Right Thing ?
