Hi All,
I have made PostgreSQL to compile on linux using sun studio with
spinlock sup****t. The patch is attached. Here is the explanation of
changes I made:
I renamed the following files
solaris_x86.s
solaris_sparch.s
to
sunstudio_x86.s
sunstudio_sparch.s
because the code is used on linux as well and is not related to solaris
but sunstudio.
I added the detection of Sun Studio to configure script, changed the
template for linux, so it gives same settings for sun studio as for
solaris.
Finally, I changed the #ifdef of __sun macro to __SUNPRO_C macro in
s_lock.h. Macro __sun is defined on solaris by both gcc and sun studio
and it is not defined on linux. Macro __SUNPRO_C is defined on linux as
well as solaris by sun studio and is never defined by gcc.
I tested the patch (build process & make check) without any problems on:
x86, solaris nevada build 79; gcc 3.4.3 (csl-sol210-3_4-20050802)
x86, solaris nevada build 79; sun studio 12
x86, debian etch, gcc 4.1.2 (20061115)
x86, debian etch, sun studio 12
sparc, solaris 10U3, gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath)
sparc, solaris 10U3, sun studio 12
I do not have an access to linux sparc machine.
Thanks for your comments.
Cheers
Julo
