Is this thing on? Cross-compiling for ARM
by Erik Winkels 26 Sep '20

26 Sep '20

Hi all, Not sure if this is still the place to be for ECL questions but here it goes: I'm having issues cross-compiling ECL for ARM and since this is actually the first time I'm cross-compiling stuff ever I'm kinda stuck. I want to cross-compile for ARM, *but* it is not for Android it is for Sailfish OS. There's an (unofficial) ECL package available for it but I cannot find a way to contact the author and also don't want to depend on it. On my Void Linux machine I've installed `cross-arm-linux-gnueabi` and can do a `./configure --host=arm-linux-gnueabi` but when I do `make` I get the following errors: ``` dpp: /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d -> list.o.c Unknown symbol: mp::compare-and-swap-car Unknown symbol: mp::atomic-incf-car Unknown symbol: mp::compare-and-swap-cdr Unknown symbol: mp::atomic-incf-cdr /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_compare_and_swap_car': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:670:26: error: 'unknown' undeclared (first use in this function) return ecl_compare_and_swap(&ECL_CONS_CAR(x), old, new); ^~~~~~~ /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:670:26: note: each undeclared identifier is reported only once for each function it appears in /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_atomic_incf_car': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:678:26: error: 'unknown' undeclared (first use in this function) return ecl_atomic_incf(&ECL_CONS_CAR(x), increment); ^~~~~~~ /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_compare_and_swap_cdr': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:686:26: error: 'unknown' undeclared (first use in this function) return ecl_compare_and_swap(&ECL_CONS_CDR(x), old, new); ^~~~~~~ /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d: In function 'mp_atomic_incf_cdr': /home/brainrot/projects/eclrepl/3rd-party/ecl-git/src/c/list.d:694:26: error: 'unknown' undeclared (first use in this function) return ecl_atomic_incf(&ECL_CONS_CDR(x), increment); ^~~~~~~ make[2]: *** [Makefile:88: list.o] Error 1 make[2]: Leaving directory '/home/brainrot/projects/eclrepl/3rd-party/ecl-git/build/c' make[1]: *** [Makefile:144: libeclmin.a] Error 2 make[1]: Leaving directory '/home/brainrot/projects/eclrepl/3rd-party/ecl-git/build' make: *** [Makefile:72: all] Error 2 ``` I get the feeling I'm forgetting some necessary steps. Thanks, Erik

Raspberry Pi test results
by Dave Richards 06 Jan '20

06 Jan '20

These are the results of testing ECL on a Raspberry Pi 3B+ running Raspbian Buster. Because the Raspberry Pi 3B+ has only 1G of RAM and the default swap size for Raspbian Buster is 100M it is highly recommended that you extend the swap size to something larger. I use 1G. Instructions for doing this are located at: https://wpitchoune.net/tricks/raspberry_pi3_increase_swap_size.html (I was unable to build Ironclad successfully without doing this.) My build configuration is: ./configure \ --enable-shared \ --enable-threads \ --enable-boehm=system \ --enable-libatomic=system \ --enable-gmp=system \ --enable-c99complex \ --enable-unicode=32 \ --enable-smallcons \ --with-tcp \ --with-serve-event \ --with-clos-streams \ --with-cmuformat \ --with-asdf \ --without-defsystem \ --with-cmp \ --with-bytecmp \ --with-dffi=included \ --with-fpe \ --with-signed-zero \ --with-ieee-fp \ --prefix=${HOME}/ecl The FPU on the Raspberry Pi does not generate CPUexceptions, which prevents Linux from generating SIGFPE signals, which prevents ECL from detecting floating-point errors and delivering appropriate error conditions. The patch below causes ECL to poll for floating-point errors (rather than relying on SIGFPEs). This situation is properly detected by 'make check'. diff --git a/src/aclocal.m4 b/src/aclocal.m4 index d1e626a7..ffcd1ad3 100644 --- a/src/aclocal.m4 +++ b/src/aclocal.m4 @@ -865,6 +865,10 @@ case "${host_cpu}" in ECL_FPE_CODE="arch/fpe_x86.c" AC_MSG_RESULT([x86_64]) ;; + arm* ) + ECL_FPE_CODE="arch/fpe_fenv.c" + AC_MSG_RESULT([arm]) + ;; *) ECL_FPE_CODE="arch/fpe_none.c" AC_MSG_RESULT([not available]) (src/configure needs to be re-generated.)

[ecl 20.1.x][rc testing]
by Daniel Kochmański 03 Jan '20

03 Jan '20

Dear All, After three years of development we are closing to a new release. During this time many important features and fixes has been made. We also have a new co-maintainer of the project – Marius Gerbershagen, what is a fantastic news (especially from a bus-factor perspective :-). If you have spare machines (especially on uncommon architectures/ operating systems), it would be very helpful if you could help with testing. I'm tracking testing progress here: https://gitlab.com/embeddable-common-lisp/ecl/issues/333 there is no need to limit yourself to the mentioned platforms and it is possible that we will omit some listed there, so please treat it more like a wishlist than an actual roadmap. We are especially interested in regressions (that is issues which are not present in 16.1.3 but occur in the current develop branch) - of course if you encounter other problems please report them too, but they will be most likely addressed after the release. Thank you for your help; I hope that we will be able to release the new version on January 2020. As a side note, I've been invited to give a talk at the European Lisp Symposium this year about ECL. Currently I'm working on the compiler documentation and refactoring as well as the IR visualizer, but these changes will be proposed after there release.

FP exceptions on Raspberry Pi
by Dave Richards 31 Dec '19

31 Dec '19

It appears that the VFP unit on the Raspberry Pi does not generate FPU exceptions. Therefore, no SIGFPE is generated and cannot be handled by ECL. This causes numerous 'make check' test failures. I am working on a patch. I am not very familiar with the ECL C environment so I am sure the patch will need some help. The approach is as follows: 1. There is no value in registering a SIGFPE handler. For the ARM I will just not register the handler at all. 2. I will created an arch/fpe_arm.c file. I will re-define the macro to read the FPSCR register and check for exception bits being set. If any are I will call a C function that will disambiguate which exception to map to a condition and signal the condition. 3. I was planning on creating a static inline function for this purpose right inside fpe_arm.c but if it should go somewhere else I'd be happy to put it there. The inline thing is just an excuse for sticking in the fpe_arm.c file. In reality it's probably better to make a C function call to do the heavy lifting rather than making each FPE check pay for it.

The European Lisp Symposium 2020 invites high quality papers about novel research results, insights and lessons learned from practical applications, and educational perspectives. We also encourage submissions about known ideas as long as they are presented in a new setting and/or in a highly elegant way. This year's focus will be directed towards "Compilers". We especially invite submissions in the following areas: - Compiler techniques - Compiler passes - Compiler compilers - Showcasing of industrial or experimental compilers - Code generation - Compiler verification - Compiler optimizations - JIT compilers Contributions are also welcome in other areas, including but not limited to: - Context-, aspect-, domain-oriented and generative programming - Macro-, reflective-, meta- and/or rule-based development approaches - Language design and implementation - Language integration, inter-operation and deployment - Development methodologies, support and environments - Educational approaches and perspectives - Experience reports and case studies Technical Program ~~~~~~~~~~~~~~~~~ We invite submissions in the following forms: * Papers: Technical papers of up to 15 pages that describe original results or explain known ideas in new and elegant ways. * Demonstrations: Abstracts of up to 4 pages for demonstrations of tools, libraries, and applications. * Tutorials: Abstracts of up to 4 pages for in-depth presentations about topics of special interest for at least 90 minutes and up to 180 minutes. All submissions should be formatted following the ACM SIGS guidelines and include ACM Computing Classification System 2012 concepts and terms. Submissions should be uploaded to Easy Chair, at the following http://www.easychair.org/conferences/?conf=els2020 Note: to help us with the review process please indicate the type of submission by entering either "paper", "demo", or "tutorial" in the Keywords field.
