Actually these are all OK. cross setup sometimes has issues (e.g. nfs automount at boot not working) these tests hit first and fail. When testing is resumed the failures stick.

Indeed. current list of failures: Currently debugging the math errors, they are regression from recent rework for reviews.

Here's my analysis of the issue so far (I don't have prior builds to corroborate here). The failures are following | Failure: acos (inf): Exception "Invalid operation" not set | Failure: acos (-inf): Exception "Invalid operation" not set | Failure: acos (1.125): Exception "Invalid operation" not set | Failure: acos (-1.125): Exception "Invalid operation" not set | Failure: acos (max_value): Exception "Invalid operation" not set | Failure: acos (-max_value): Exception "Invalid operation" not set ... ... | similarly 6 for each of acos_downward(), acos_towardzero (), acos_upward () Simple testcase which confirms that Invalid Exception is *not* being raised | double in = __builtin_inf (); | acos(in); | pass = fetestexcept(FE_INVALID); Exception *is* raised for @in = __builtin_nans("") Now acos can come from 2 places depending on LIBM_SVID_COMPAT - math/w_acos_template.c <-- sets errno only - math/w_acos_compat.c <-- raises exception FE_INVALID For ARC, 1st variant is building, so explicit exception is NOT raised. Is this the issue ? Or is Invalid Exception supposed to be set by the prologue in acos (both variants) which looks like following: __acos (double x) { if (__builtin_expect ((__builtin_isgreater(fabs (x), 1.0)), 0)) isgreater() is not unordered so it is not supposed to raise exception unless signaling so it can't be, and fabs() doesn't seem be doing much except clipping off some bits. So I'm confused where the issue is

LIBM_SVID_COMPAT is a compat feature, thus not relevant and always off for new ports. It's a bug in the testsuite that it doesn't handle that case yet. Andreas.

The implementation in sysdeps/ieee754/dbl-64/e_asin.c raises the exception by doing an Inf / Inf computation. u.i[HIGH_HALF]=0x7ff00000; v.i[HIGH_HALF]=0x7ff00000; u.i[LOW_HALF]=0; v.i[LOW_HALF]=0; return u.x/v.x; https://gcc.gnu.org/bugzilla/show_bug.cgi?id=95115 The right place to fix this is in GCC, to stop it constant-folding Inf / Inf when flag_trapping_math. That should be a straightforward fix. It would also be reasonable to change the above code to just "return 0.0 / 0.0;", as a simpler, more idiomatic way of returning a NaN with "invalid" raised. (Any code constructing infinities / NaNs via bit patterns likely predates built-in functions that can be used to represent such values directly. Though the GCC bug means a literal replacement with "return __builtin_inf () / __builtin_inf ();" wouldn't fix the present problem.)

I almost forgot that this was upstream gcc-10 for ARC too (and problem doesn't happen with gcc-9). So my glibc updates didn't trigger this, phew ! > The right place to fix this is in GCC, to stop it constant-folding Inf / > Inf when flag_trapping_math.

Note this is bug 14231 (covering test-vfprintf as well, which also requires a large amount of memory). Although arguably the real bug is in the printf code, which shouldn't need so much memory (bugs 17829, 21127, 24988, maybe others).
Hi, This patchset implements glibc port to ARC HS48x processor from Synopsys. git@github.com:foss-for-synopsys-dwc-arc-processors/glibc.git upstream-v7 v7: * Addresses review comments from Adhemerval Zanella and Florian Weimer (many thx to you both) * Dropped ARC specific semaphore.h (following upstream 1270fbaaeebe) * ARC specific dl-runtime.h (following upstream 8dbb7a08ec52) * ARC specific math-use-builtins.h and dropped ARC specific sqrt/fma routines (math-use-builtins.h will be disintegrated once done upstream) * setjmp/longjmp to save GP, no need to save r25 (thread pointer) * makecontext/startcontext use r14/r15 (vs. r13/r14) * flatten out register file in mcontext_t (remove scratch/callee) * Use of 'C' comments in asm code, LDR/STR macros * Use of L (..) in asm code * Dropped asm global register r25 specification for thread pointer and rely on __builtin_thread_pointer * NEWS update rewording * Sweeping update of Copyright year 2020 v6: * Dropped 11/14: merged upstream * _FPU_SETS() inline asm reworked * Introduce fixup-asm-unistd.h to elide 32-bit time, offset syscalls and regenerate arch-syscall.h * Fix snafu in updating build-many-glibcs for ARC * More code sytle fixes flagged by Joseph v5: * Big Endian formally supported as multi-ABI * Removed code for ARC700 processors * Hard-float code updates: fegetmode, fesetround, feupdateenv * socket-constant.h update for 64-bit ABI spun off as standalone patch * __syscall_error made glibc_private * math ulps regen * gmp-mparam.h removed * lint fixes as flagged by Joseph v4: * Dropped 1/17: Merged upstream * Dropped 17/17: - 64-bit time/offset code chunked up into respective patches * sysctl removed * Updated README for arc gnu triplet * Updated install files for ARC gcc/binutils requirements * Updated NEWS with brief ISA/ABI info v3: * Support for Hardware Floating Point * 64-bit time and offsets ABI (although all such changes are confined to a single patch) v5: https://sourceware.org/pipermail/libc-alpha/2020-April/112657.html v4: https://sourceware.org/pipermail/libc-alpha/2020-March/111855.html v3: https://sourceware.org/legacy-ml/libc-alpha/2020-03/msg00167.html v2: https://sourceware.org/legacy-ml/libc-alpha/2019-01/msg00681.html v1: https://sourceware.org/legacy-ml/libc-alpha/2018-12/msg00678.html Documentation: -------------- (a) ABI doc: https://github.com/foss-for-synopsys-dwc-arc-processors/toolchain/wiki/files/ARCv2_ABI.pdf (b) Programmer's Reference Manual (PRM) : needs a download request to be filled https://www.synopsys.com/dw/ipdir.php?ds=arc-hs44-hs46-hs48 https://www.synopsys.com/dw/doc.php/ds/cc/programmers-reference-manual-ARC-HS.pdf Test Results: -------------- (a) build-many-glibcs.py | Summary of test results: | 1251 PASS | 15 XFAIL (b) Full testsuite ran in a cross compile setup using buildroot on HSDK development platform.
