[Bug modula2/92148] gm2: race condition building gm2 on trunk
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92148 --- Comment #1 from Gaius Mulley --- is this still true? As I've git pushed a number of dependency fixes to the master branch (in gm2/Make-lang.in). It built with make -j 24 on amd64 debian stretch.
[Bug modula2/92147] gm2: modula-2 fails to build on powerpc-linux-gnu
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92147 --- Comment #1 from Gaius Mulley --- I've just seen gm2 master branch build successfully on powerpc64le-unknown-linux-gnu (make -j 24). It is currently running the regression tests - looks like it will fail on 15 tests - 6 more than the amd64 (6 tests should fail on every platform). The current master also contains the new coroutine implementation using __gthr.h - which also passes. Just finished the testsuite with: # of expected passes 11247 # of unexpected failures 13 # of unresolved testcases 1 On Fri, 18 Oct 2019 at 11:23, doko at debian dot org < gcc-bugzi...@gcc.gnu.org> wrote: > https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92147 > > Matthias Klose changed: > >What|Removed |Added > > > CC| |gaiusmod2 at gmail dot com > > -- > You are receiving this mail because: > You are on the CC list for the bug.

Prior to the patch it used the default C long double type but many of the intrinsic functions were broken. Currently with the patch gcc120 has no regression test failures and gcc135 (yesterday with manual configure intervention) was at 96 failures in the m2 testsuite. I suspect configure confusion and hence using TARGET_DEFAULT_LONG_DOUBLE_128 and TARGET_IEEEQUAD_DEFAULT should resolve it.
[Bug modula2/113511] lack of libm2 ABI compatibility on powerpc platforms

(which really only > change the C language ABI!). Of course calls to libm are subject to the > C language ABI. ok yes. So m2's longreal data type uses ieeelongdouble throughout by default on powerpc - that would be clean. In principle could all the C interface from m2 code convert the longreal representation to glibc long double and visa versa? So for example in the case of libm.def change libm.def from a DEFINITION FOR "C" to an ordinary m2 definition module. Introduce libm.c which for non power platforms just passes calls though to C. On powerpc (without an IEEE128 glibc) it will convert __float128 onto the underlying long double representation. > Does the language standard have anything to say here? I suppose there's > no ABI documents for M2 for various targets, so eventually C interoperability > language in the standard directs at the common sense? It leaves much to be implementation defined :-) The gcc/m2/gm2-libs-iso/LowLong.def provides setMode which could be used to control the behaviour of the above conversions. The size of the set Modes and their meaning is implementation defined. Possibly it might be implemented: Bit 0: issue an error and abort if the underlying long double support in glibc does not match the longreal in m2. Bit 1: issue a single warning if the underlying long double support in glibc does not match the longreal in m2 and then attempt conversion. Bit 2: raise an exception if the underlying long double support in glibc does not match the longreal in m2. Bit 3: raise an exception if the conversion between longreal and glibc C long double representations exceeds range. Bit 4.. More bits to control conversion behaviour. [ as a start ]
