Marlin: With eeprom enable and 2 extruders, fail compile

Created on 8 Jan 2017 · 13Comments · Source: MarlinFirmware/Marlin

When you configure:

#define EXTRUDERS 2

#define TEMP_SENSOR_0 -1 // or the sensor than you want
#define TEMP_SENSOR_1 -1 // or the sensor than you want
#define TEMP_SENSOR_2 0
#define TEMP_SENSOR_3 0
#define TEMP_SENSOR_BED 1 // or the sensor than you want

#define EEPROM_SETTINGS

happen this:

Arduino:1.8.0 (Mac OS X), Tarjeta:"Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

sketch/temperature.cpp: In function 'manage_heater':
temperature.cpp:797: error: unable to find a register to spill in class 'POINTER_REGS'
 }
 ^
temperature.cpp:797: error: this is the insn:
(insn 109 106 111 5 (set (reg:SF 110 [ D.2333 ])
        (mem:SF (post_inc:HI (reg:HI 111 [ ivtmp.126 ])) [7 MEM[base: _141, offset: 0B]+0 S4 A8])) sketch/temperature.cpp:684 100 {*movsf}
     (expr_list:REG_INC (reg:HI 111 [ ivtmp.126 ])
        (nil)))
sketch/temperature.cpp:797: confused by earlier errors, bailing out

collect2: error: ld returned 1 exit status

unable to find a register to spill in class 'POINTER_REGS'

happen in RC8 and RCBUGFIX

some idea?

No need to jump through hoops or download earlier versions. I am compiling Marlin-1.1.0-RC8 on Windows 10, Arduino 1.8.1.

To fix this, find the function giving the error. In my case it was temperature.cpp:manage_heater()

Simply copy the function declaration and paste it directly above.
Remove the trailing { and add
__attribute__((__optimize__("O2"))); to the end of the line.

Before:

void Temperature::manage_heater() {

after

void Temperature::manage_heater() __attribute__((__optimize__("O2")));
void Temperature::manage_heater() {

Recompile and all is well.

I hope that helps someone.

Try a different version of Arduino. Known issue.

What version are you use?
I test
1.8.0 fail
1.6.13 fail
1.6.12 fail

fbarcenas on 8 Jan 2017

If a different version won't work, try reshuffling some code. I am using
the latest. I assume you are using the one from Arduino.cc?

I use yes of the original website of arduino.

Nobody more happen this?

With version 1.6.8 and WITHOUT update the boards, WORKS.

fbarcenas on 9 Jan 2017

As Makaira points out, it is a well known issue. Try downloading earlier
versions of Arduino or shuffling some code around.

WORKS PERFECTLY!!!!!
Problem solved, also with the last RCBUGFIX works!

I think than this change must apply in the actual rcbugfix!

fbarcenas on 22 Feb 2017

I tried the fix

void Temperature::manage_heater() __attribute__((__optimize__("O2")));
void Temperature::manage_heater() {

and get this:

sketch\temperature.cpp:665:69: warning: declaration of 'static void Temperature::manage_heater()' outside of class is not definition [-fpermissive]

 void Temperature::manage_heater() __attribute__((__optimize__("O2")));

ANy opinions: Using latest ARduino and rc 1.1.0 rc8

pmbroth on 24 Apr 2017

This is already done in RCBugFix (due to be released as 1.1.0 in a few days). So I suggest upgrading. You can see in the header file, temperature.h:

    static void manage_heater()  __attribute__((__optimize__("O2")));

Thank you...
