* [PATCH] libstdc++: Fix build for AVR [PR115481, PR111639] [not found] ` <bug-115481-3249-15VyLpgmpe@http.gcc.gnu.org/bugzilla/> @ 2024-06-14 17:37 ` Detlef Vollmann 2024-06-14 17:45 ` Xi Ruoyao 0 siblings, 1 reply; 7+ messages in thread From: Detlef Vollmann @ 2024-06-14 17:37 UTC (permalink / raw) To: gcc Patches, libstdc++; +Cc: gcc-bugzilla [-- Attachment #1: Type: text/plain, Size: 283 bytes --] The attached patch fixes 115481 and 111639. It was tested against avr-libc 2.0.0 (which has *f as macros), 2.1.0 (which has *f as functions, but no long double), and 2.2.0 (which has long double functions). Only the libstdc++ build was tested, not the resulting library. Detlef [-- Attachment #2: fix-avr-math.patch --] [-- Type: text/x-patch, Size: 62319 bytes --] commit 9112ae579f73b249e9515d5ac9ddc3a76b067c39 Author: Detlef Vollmann <dv@vollmann.ch> Date: Fri Jun 14 14:34:31 2024 +0200 libstdc++-v3: detect math functions when using avr-libc and handle macros Different versions of avr-libc have different definitions of math functions: - 2.0.0 and earlier have float versions as macros - 2.1.0 has float versions as proper functions, but no long double versions - 2.2.0 has long double versions This commit tells configure to always check if these functions are available. It also #undef's any macros. libstdc++-v3/ChangeLog: * crossconfig.m4 [avr*-*-*]: Add compile-checks for float and long double functions. * configure: Regenerate. * src/c++98/math_stubs_float.cc: #undef any macros. diff --git a/libstdc++-v3/configure b/libstdc++-v3/configure index 5645e991af7..17dbae7bd87 100755 --- a/libstdc++-v3/configure +++ b/libstdc++-v3/configure @@ -5080,7 +5080,7 @@ else We can't simply define LARGE_OFF_T to be 9223372036854775807, since some C++ compilers masquerading as C compilers incorrectly reject 9223372036854775807. */ -#define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62)) +#define LARGE_OFF_T ((((off_t) 1 << 31) << 31) - 1 + (((off_t) 1 << 31) << 31)) int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721 && LARGE_OFF_T % 2147483647 == 1) ? 1 : -1]; @@ -5126,7 +5126,7 @@ else We can't simply define LARGE_OFF_T to be 9223372036854775807, since some C++ compilers masquerading as C compilers incorrectly reject 9223372036854775807. */ -#define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62)) +#define LARGE_OFF_T ((((off_t) 1 << 31) << 31) - 1 + (((off_t) 1 << 31) << 31)) int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721 && LARGE_OFF_T % 2147483647 == 1) ? 1 : -1]; @@ -5150,7 +5150,7 @@ rm -f core conftest.err conftest.$ac_objext conftest.$ac_ext We can't simply define LARGE_OFF_T to be 9223372036854775807, since some C++ compilers masquerading as C compilers incorrectly reject 9223372036854775807. */ -#define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62)) +#define LARGE_OFF_T ((((off_t) 1 << 31) << 31) - 1 + (((off_t) 1 << 31) << 31)) int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721 && LARGE_OFF_T % 2147483647 == 1) ? 1 : -1]; @@ -5195,7 +5195,7 @@ else We can't simply define LARGE_OFF_T to be 9223372036854775807, since some C++ compilers masquerading as C compilers incorrectly reject 9223372036854775807. */ -#define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62)) +#define LARGE_OFF_T ((((off_t) 1 << 31) << 31) - 1 + (((off_t) 1 << 31) << 31)) int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721 && LARGE_OFF_T % 2147483647 == 1) ? 1 : -1]; @@ -5219,7 +5219,7 @@ rm -f core conftest.err conftest.$ac_objext conftest.$ac_ext We can't simply define LARGE_OFF_T to be 9223372036854775807, since some C++ compilers masquerading as C compilers incorrectly reject 9223372036854775807. */ -#define LARGE_OFF_T (((off_t) 1 << 62) - 1 + ((off_t) 1 << 62)) +#define LARGE_OFF_T ((((off_t) 1 << 31) << 31) - 1 + (((off_t) 1 << 31) << 31)) int off_t_is_large[(LARGE_OFF_T % 2147483629 == 721 && LARGE_OFF_T % 2147483647 == 1) ? 1 : -1]; @@ -28628,51 +28628,2354 @@ case "${host}" in ;; avr*-*-*) - $as_echo "#define HAVE_ACOSF 1" >>confdefs.h - $as_echo "#define HAVE_ASINF 1" >>confdefs.h - $as_echo "#define HAVE_ATAN2F 1" >>confdefs.h - $as_echo "#define HAVE_ATANF 1" >>confdefs.h + { $as_echo "$as_me:${as_lineno-$LINENO}: checking for acosf declaration" >&5 +$as_echo_n "checking for acosf declaration...

This version of the patch doesn't have the problem (this was the easy part :-) However, my tests show that this is only a partial solution. But I believe the patch is correct, and it solves the build problems for libstdc++ for AVR target. However, at least for avr-libc 2.0.0 (the version that has the *f functions as macros) it's not a complete patch: std::sinf etc, and std::sinl etc are not provided (::sinf and ::sinl are not provided either). std::sin exists and has overloads for float, double and lon double. And calling std::sin(float) only works if the call is inlined, otherwise I get a linker error ".text._ZSt3sinf[_ZSt3sinf]+0x10): undefined reference to `sinf'". I don't get a similar error for sinl when calling std::sin(long double). I didn't have time to dig into the build of libstdc++ to find out what the difference is. For avr-libc 2.1.0 (that provides real *f functions but no *l) I still get the error that std::sinl is not provided but none of the other problems. For avr-libc 2.2.0 (that provides real *f and *l functions) I don't get any of the problems above. But for all three avr-libc versions I get the problem that the C++ sin(long double) returns a different value than the C sinl (which is just another linker name for sin): I don't really know about floating point representations, but it looks like the C version fills the mantissa for a long double return with 0, while the C++ version has bits there. Looking at the implementation in math_stubs_long_double.cc, which only calls the double version and promotes the return to long double this looks strange. But probably libstdc++ is compiled with different flags than my test program. And if I convert the long double result back to double I get the same value as for C, so it's not really wrong, but it's irritating... So again, I think my patch helps, but is not a complete solution.

Please regenerate using *vanilla* autoconf-2.69. Sorry, I was surprised myself, when I looked at the changes. But after looking at the actual change I thought it doesn't matter. I used Debian's version, I'll try to get a vanilla version working tomorrow (I actually plan anyway to run a test with the built libstdc++ on simulavr).

Apart from that, only being a core simulator, you can test for more cores than covered by simulavr. simulavr supports devices that cover the following 8 multilib variants: avr2 tiny-stack avr25 avr25/tiny-stack avr4 avr5 avr51 avr6 out of the 19 variants available in avr-gcc, like avr3, avr31, avrtiny, and all the avrxmega[2-7] variants that can be used with avrtest. avrtest comes with board descriptions that cover a variety of all the different cores. avrtest board descriptions usually supply more RAM than the actual device has, which allows more PASSes due to less out-of-memory FAILs.

But right now I'm fighting against an ICE in cmath, i.e. so far any tests of cmath fail... I'll investigate this tomorrow and decide then what I'll do...
