Teensyduino 1.58 Beta #1 (updated toolchain trial)

Here is a first beta test for Teensyduino 1.58.

This is an experiment to update the gcc toolchain from 5.4.1 to 11.3.1. Please try as many programs and libraries as you can. If gcc 11.3.1 has serious compatibility or performance issues, I'll revert back to 5.4.1. If it looks promising, I'll work on a newlib rebuild without C++ exception overhead and installers for MacOS and the other Linux architectures, and packages for Arduino CLI & IDE2.


Linux 64 bit:

Windows:
https://www.pjrc.com/teensy/td_158-beta1/TeensyduinoInstall.exe


Changes since Teensyduino 1.57:

Updated toolchain to gcc 11.3.1 for Teensy LC, 3.x, 4.x
Update core library for gcc 11.3.1
Update Wire library for gcc 11.3.1
Update teensy_size for gcc 11.3.1
FlexIO_t4 FlexSerial support more baud rates (KurtE)
AudioEffectEnvelope fix release name conflict (Jonathan Oakley)
Add audio DynamicPatching example (Jonathan Oakley)
Audio design tool fix control name on export (Jonathan Oakley)
USBHost_t36 improved HID device diagnostic info (KurtE)
Improve C & C++ library access to Teensy 3 & 4 RTC hardware
Audio use IntervalTimer for updates if no hardware update available

Good Morning all
Downloaded and installed in IDE1.8.19 no problem on a windows 10x64. IDE2 isn;t showing the update though for 1.58-beta1 not sure if this was intentional?

Also, I seem to remember that you had a perl script that you put together to test all the libraries during T4.x beta testing. Maybe can run that to say some time at least for the T4's. Unfortunately I never could get that working on a windows machine.

Now for some testing.
 
Downloaded on my Windows 11 machine. But for whatever reason it does not like my Arduino 1.8.19 directory.

So cannot try on IDE2.

Next up probably fresh install

Oops missed the IDE2 wasn't ready thanks for pointing that out.

I forgot to mention that I installed 1.58b1 on a clean copy of IDE1.8.19 without an issue so might be the difference.
 
Thanks @mjs513 for letting me know that the links in post #1 are wrong, the point to 1.57 beta 1. They point to: xxx/td_157-beta1/TeensyduinoInstall.exe

Should be: https://www.pjrc.com/teensy/td_158-beta1/TeensyduinoInstall.exe

That one installed on my dirty 1.8.19

Now to try it out. Although not looking forward to building lots of stuff on 1.8.19... IDE 2 builds so much faster. Also, nice that they monitor file changes, and other that some real quirks
with the UI, like magic text cursor (which there is work around for), is a lot nicer... But...
 
@Paul, @KurtE and all
Test 3 of the latest sketches we have been working on. Wacom tablets, keyboard HID updates and a unique sketch. Mostly anti-aliasing warnings in USBHost but for the custom sketch getting an

-----
T3.6 = No errors
T3.2 = No errors
 
Note: After my install it appears like it is running 1.57 still... Guess next clean install.

Edit: Clean install now shows 1.58B1...

Good Morning all
Downloaded and installed in IDE1.8.19 no problem on a windows 10x64. IDE2 isn;t showing the update though for 1.58-beta1 not sure if this was intentional?

Also, I seem to remember that you had a perl script that you put together to test all the libraries during T4.x beta testing. Maybe can run that to say some time at least for the T4's. Unfortunately I never could get that working on a windows machine.

Now for some testing.
Click to expand...

I was also wondering if you ran your perl scripts? And have a list of things with issues that we should be looking at?

Also curious on what things are gained by this and where problems are more likely to be lurking?

For example, if the biggest is gain is to allow some more modern stuff in let's say templates or std:: classes, I more or less seldom if ever use them, so I am less likely to find any issues there.
Hopefully others who use it, will test those areas.

Now back to testing some random stuff.

Note: some of the code that the compiler flags, makes me want to pull out a few more strands of hair. Like:
Code: 
class USBFilesystem : public FS, public USBFSBase
{
...
	operator bool() {
		[COLOR="#FF0000"]Device_t *dev = *(Device_t * volatile *)&device;[/COLOR]
		return dev != nullptr;
	}
Code: 
:\Users\kurte\Documents\Arduino\libraries\USBHost_T36\USBHost_t36.h:2479:44: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]
 2479 |                 Device_t *dev = *(Device_t * volatile *)&device;
      |                                            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What is gained by this versus:
Code: 
operator bool() { return device != nullptr;}
What does volatile gain you here? since this is the only reference to that member variable within that method?
Note: There is another similar construct within USBHost_t36.h
 
Yeah, it prints warnings on a lot of libraries, especially about misleading indentation. I found a couple with errors, usually about time_t.

Now to try it out. Although not looking forward to building lots of stuff on 1.8.19... IDE 2 builds so much faster.
Click to expand...

I'll try to package up files for IDE2. I still haven't written a nice script to automate this...
 
For my TeensyMIDIPolySynth (now two separate modules connected via 500kbps shared Serial4: Teensy-MIDI-RA8875-PolySynth-Audio running on a T4.0 as "Serial", & Teensy-MIDI-RA8875-PolySynth-Display running on a T4.1 as "Serial + MIDI", both compiled with "Smallest Code" optimization), the audio T4.0 compiled fine, no errors, no warnings. The T4.1 compiled to completion, but threw the following (similar to mjs513 report):

Still traveling back from our Labor Day holiday weekend campout, so will test on the actual TeensyMIDIPolySynth hardware later this evening when we get back home.

@kd5rxt-mark - Yes a lot of those are the same one that @mjs513 and me mentioned.

Locally I updated the bool() to what I mentioned and removed those compiler warnings.

Still have one in the USBHost I noticed:
Code: 
C:\Users\kurte\Documents\Arduino\libraries\USBHost_T36\MassStorageDriver.cpp: In member function 'virtual void USBDrive::disconnect()':
C:\Users\kurte\Documents\Arduino\libraries\USBHost_T36\MassStorageDriver.cpp:211:15: warning: 'void* memset(void*, int, size_t)' clearing an object of non-trivial type 'struct msDriveInfo_t'; use assignment or value-initialization instead [-Wclass-memaccess]
  211 |         memset(&msDriveInfo, 0, sizeof(msDriveInfo_t));
      |         ~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I

I guess one question is, do we actually change any of the code like this not to use memset? Ignore the warnings? Change the compiler settings to not see these? ...
 
Ok, IDE2 packages uploaded. Updating the package index is still a manual process, so please let me know if I got some detail wrong? Ran a quick test on Linux and it seems to work.

I also changed the old compiler to version 5.4.1 rather than 1.56.1. So it might want to do updates even if you have a prior version installed. But in hindsight, calling the toolchain a Teensyduino version number just wasn't a good idea. Needs to get fixed sometime, and that time is now.

Click to expand...

This is the joy of updating the toolchain. We get a ton of new compiler warnings about stuff that really should get updated. Most are probably harmless, but they're also probably about things that were never quite 100% correct but worked anyway.

I believe this warning is trying to tell us that the USBDrive class is too complicated to simply be cleared by memset(). Maybe it's because it inherits from 2 other classes? Maybe something about SdFat FsBlockDeviceInterface class matters?

Actually it is not clearing a class but a structure:
Code: 
typedef struct {
	bool connected   = false; // Device is connected

Locally I removed the warning by casting it to (void*)
It is interesting that the disconnect does clear a few of members and then hits it with memset:
Code: 
	msDriveInfo.connected = false;
	msDriveInfo.initialized = false;
	memset((void*)&msDriveInfo, 0, sizeof(msDriveInfo_t));

Not sure, I figured it was more likely that it contained two other structures.
Will experiment later. As I mentioned I simply cast the pointer to void* in the memset.

/CODE][/QUOTE]

As for the snprintf, I am not sure how to fix.
[CODE]    breakTime(dt, dtf);
    snprintf(ctimebuf, sizeof(ctimebuf), "%04u%02u%02uT%02u%02u%02u",
             dtf.year + 1900, dtf.mon + 1, dtf.mday, dtf.hour, dtf.min,
             dtf.sec);
It is complaining that for example dtf.mday is a byte that it might get trancated... But the last time I checked there are no months that have 100+ days in them ;)

@Paul, @KurtE and all
Test 3 of the latest sketches we have been working on. Wacom tablets, keyboard HID updates and a unique sketch. Mostly anti-aliasing warnings in USBHost but for the custom sketch getting an

relocation truncated to fit: R_ARM_PREL31 against symbol

for the T4.x boards.

@Paul ----- Was able to duplicate the error with a simple sketch using a simple vector example. If you run the following code it will compile and run correctly:
Code: 
#include <Streaming.h>
#define cout Serial

#include <vector>
using namespace std;

void setup() {
  cout.begin(9600 && millis() < 5000);

 // initializer list
  std::vector<int> vector1 = {1, 2, 3, 4, 5};

  // uniform initialization
  std::vector<int> vector2{6, 7, 8, 9, 10};

  // method 3
  std::vector<int> vector3(5, 12);

  cout << "vector1 = ";

  // ranged loop
  for (const int& i : vector1) {
    cout << i << "  ";
  }

  cout << "\nvector2 = ";

  // ranged loop
  for (const int& i : vector2) {
    cout << i << "  ";
  }

  cout << "\nvector3 = ";

  // ranged loop
  for (int i : vector3) {
    cout << i << "  ";
  }

  // add the integers 6 and 7 to the vector
  //vector1.push_back(6);
  //vector1.push_back(7);

  cout << "\nUpdated Vector: ";

  for (const int& i : vector1) {
    cout << i << "  ";
  }


  
}

void loop() {
  // put your main code here, to run repeatedly:

}
If you uncomment the lines with vector1.push_back it will throw those errors but no clue how to fix. Trying to read google some say it was fixed with -fno-exceptions but after pointing to that it might be a linker error.

Short start here ... got working IDE2 here yesterday {changed temp to SSD as the virtual drive still fails IDE2 exec issue still unresolved}

Will work in that: Processing Teensy:1.58beta1 Update - Complete!

Have a short time before appointment ...

Fixed the issues in MTP_Teensy in my try_auto_detect_sd_media branch.
Code: 
  #pragma GCC diagnostic push
  #pragma GCC diagnostic ignored "-Wformat-truncation" /* Or "-Wformat-truncation" */
...

also moved the if(x) break; {
moved { to next line... Probably could remove the brackets.
