* [PATCH v2] ARM: asm: rename logical shift macros push pull into lspush lspull @ 2014-02-10 20:19 Victor Kamensky 2014-02-10 20:19 ` Victor Kamensky 0 siblings, 1 reply; 11+ messages in thread From: Victor Kamensky @ 2014-02-10 20:19 UTC (permalink / raw) To: linux-arm-kernel Hi Guys, This patch renames 'push' and 'pull' logical shift macros in arm assembler.h, so it could be included into .S file that use 'push' as instruction. That was discussed on [1]. Will Deacon suggested the idea of the patch. As far as code change concerned - the change is really only macros rename and change in all places where macros are used. Even if diff may seem big it is very simple change. Changes from previous version: - Now instead of changing kvm .S files that use push instruction patch rename push and pull - This patch is submitted separately from ARM V7 BE KVM series Testing: - Was tested on rmk/for-next branch. TC2 LE and BE images were built and run - Verified build of all 118 images under arch/arm/configs and with objdump dump verified that images text segment do not change compared with base line (modulo buildid (disabled), some initramfs addresses) Will, I added your name under 'Suggested-by:', please let me know if you object to this.

That eliminates name conflict between 'push' logical shift macro and 'push' instruction mnemonic. That allows assembler.h to be included in .S files that use 'push' instruction.

No more so than "pull towards" and "push from". I'll blame it on the fact that the get_byte_ macros have wrong- endian numbering, which I didn't look at carefully enough ;) But I think we proved that my suggestion didn't really make things easier to understand...

For me those tokens were just symbols with specific meaning of logical shifts and selected endianness. I'll do as you decide. Quick grep over .S files under arch/arm seems 'next' and 'prev' will be OK and I did build that confirms that. One nit/question though: there are some cases where 'push' and 'pull' macros were used in macros and macro parameters were also called 'push' and 'pull'. I.e something like this: mov r3, lr, pull #\pull with rename 'pull' to 'lspull' I did not bother to rename macro parameters because they are separate, have just local context and 'lspull' is close to 'pull'. Resulting proposed diff was: - mov r3, lr, pull #\pull + mov r3, lr, lspull #\pull I assume that if we change 'push -> next' and 'pull -> prev' I will need to rename macro parameters in the same way. So it will be: + mov r3, lr, prev #\prev Is it correct? Thanks, Victor > > Nicolas ^ permalink raw reply [flat|nested] 11+ messages in thread

There is a case in ./nwfpe/entry.S file where 'next' is used as label name. I guess, it should work if macro would rename it into lsl or lsr label name. And/or we could rename the label. Wondering ... whether idea to have those macros name in way that coincides with English words would lead us to some conflict earlier or latter. With this respect lspull and lspush IMHO are somewhat better because they are sort of abbreviations.

I think it was worth exploring different alternatives, but nothing really better came out. Nicolas ^ permalink raw reply [flat|nested] 11+ messages in thread
