Trying to be more flexible in register use so the compiler can do reloads
* app/composite/gimp-composite-sse2.c: Trying to be more flexible in register use so the compiler can do reloads without running out of registers when using optimisation modes other than 2. Avoid the message "error: can't find a register in class `GENERAL_REGS' while reloading `asm'" * app/composite/gimp-composite-x86.h Use more newlines in asm() macros to ensure that gcc gets the instruction count correct. This is partially complete as of this commit.

Trying to be more flexible in register use so the compiler can do
|

reloads without running out of registers when using optimisation
|
||||
modes other than 2.

||||
Avoid the message "error: can't find a register in class
|
||||
`GENERAL_REGS' while reloading `asm'"
|
||||
|
||||
* app/composite/gimp-composite-x86.h
|
||||
Use more newlines in asm() macros to ensure that gcc gets the
|
||||
instruction count correct. This is partially complete as of this
