[PATCH 2/2] [RFC] Add IFUNC support for MIPS (v4)

[Maciej W. Rozycki]

Hi Faraz,

> 	* ld-ifunc/ifunc.exp: Enable IFUNC tests for MIPS targets
> 	* ld-mips-elf/mips-ifunc.exp: IFUNC test script

 Please use full stops at the end of sentences.

> 	* ifunc-3-n32.r, ifunc-3-n32.sym, ifunc-3-n32.t, ifunc-3-n64.r,

... and so on, and so on -- you're mixing test case sources and dumps.  
Please separate them and group functionally.  Please include subdirectory 
names and keep one file per line.  Using a shell script to generate such a 
listing is probably the easiest way.  See the existing examples.

 Missing new line here, please fix this up.  Lots of cases like this 
throughout, I won't be listing them all.

 If your editor does not automatically add a new-line character at the end 
by default, then I suggest that you review your patches manually before 
submitting -- it may be easier for you to strip these lines with `sed' on 
an otherwise ready patch file actually.

 This dump does not make sense to me, you are disassembling data.  If you 
want to verify GOT contents, then use `readelf -A'; it'll add extra 
information like symbol names to verify too.  Again, lots of other cases 
like this.

 Please resubmit with these global corrections; I haven't gone through the 
rest of your proposal as especially the last change will make your patch 
substantially different.

 Thanks,

  Maciej
