Can anyone give me instructions how to disable pie for that profile locally so I can test if that is the issue?
(In reply to Rolf Eike Beer from comment #7) > Can anyone give me instructions how to disable pie for that profile locally > so I can test if that is the issue? Something like this https://bugs.gentoo.org/641216#c3 should work. """ For that you would need to un-force USE=pic on gcc as: /etc/portage/profile/package.use.force: sys-devel/gcc -pie and then build USE=-pie gcc. """ Another thing to try is apply patches from https://bugs.gentoo.org/641474 which should switch to using correct startup files for static+default-pie case as it certainly affects 'sln' but I'm not sure it it's enough.
I have picked only the second patch from bug 641474, which did not help. Also the binutils patch did not help. Building gcc with [-pie] and the same patches _did_ help.
Did not find too much but a few hints: Reproducible in qemu-user and hangs at memcpy() call in __libc_setup_tls: https://sourceware.org/git/?p=glibc.git;a=blob;f=csu/libc-tls.c;h=1f8ddaf5430d5de3a59e3b9fe6505200119a80d2;hb=HEAD#l181 $ qemu-sparc32plus -d in_asm elf/sln ...

Created attachment 511216 [details, diff] glibc-2.26-no-memcpy-ifunc.patch __libc_setup_tls() is called before redirectors for IFUNC are configured. I'm not sure how first pass initializes those: https://sourceware.org/git/?p=glibc.git;a=blob;f=csu/libc-start.c;h=34dd1252605519dfa034c836d5c0cb732bc39243;hb=HEAD#l197 Assuming those contain garbage. Attachted a workaround to avoid memcpy() from IFUNC in __libc_setup_tls(). qemu still hangs early but at least it gets further through __libc_setup_tls().
One of the workarounds is to compile glibc with disabled multiarch: EXTRA_ECONF=--disable-multi-arch emerge -v1 glibc
(In reply to Sergei Trofimovich from comment #12) > One of the workarounds is to compile glibc with disabled multiarch: > EXTRA_ECONF=--disable-multi-arch emerge -v1 glibc Does not seem to be enough as well.
Filed https://sourceware.org/PR22638 upstream to get some guidance on safety of IFUNC usage in early startup code.
(In reply to Sergei Trofimovich from comment #14) > Filed https://sourceware.org/PR22638 upstream to get some guidance on safety > of IFUNC usage in early startup code. H.J. and Anreas pointed out IFUNCs get set up before TLS setup thus are safe to use. The problem is in assembly code for sparc which assumes PIC more is used only for DSOs. And that breaks with --enable-default-pie. Thus most of '#ifdef SHARED' should be changed to '#ifdef PIC'. The good thing is glibc-master changed IFUNC selection from assembly level to C level (and fixing PIC Once and For all there). There is a single patch needed on top of master to make sparc work: https://sourceware.org/ml/libc-alpha/2017-09/msg01140.html For glibc-2.26 it's less easy. I see a few avenues: 1. do nothing and mask <glibc-2.27 on 17.0 sparc profiles 2. backport a huge batch of patches porting IFUNC selection from assembly to C (some of the patches remove code): Adhemerval Zanella (25): nptl: Add tests for internal pthread_mutex_t offsets nptl: Define __PTHREAD_MUTEX_{NUSERS_AFTER_KIND,USE_UNION} sparc: Implement memcpy/mempcpy ifunc selection in C sparc: Implement memset/bzero ifunc selection in C sparc: Assume VIS3 support sparc: refactor sparc64 signbit{f} selector to C sparc: refactor sparc64 isnan{f} selector to C sparc: refactor sparc64 isinf{f} selector to C sparc: refactor sparc64 finite{f} selector to C sparc: refactor sparc64 nearbyint{f} selector to C sparc: refactor sparc64 lrint{f} selector to C sparc: refactor sparc64 rint{f} selector to C sparc: refactor sparc64 __mpn_mul_1 selector to C sparc: refactor sparc64 __mpn_sub_n selector to C sparc: refactor sparc64 __mpn_addmul_1 selector to C sparc: refactor sparc64 __mpn_submul_1 selector to C sparc: refactor sparc64 __mpn_add_n selector to C sparc: refactor sparc32 copysign selector to C sparc: refactor sparc32 fabs{f} selector to C sparc: refactor sparc32 llrint{f} selector to C sparc: refactor sparc32 rint{f} selector to C sparc: refactor sparc32 nearbyint{f} selector to C sparc: refactor cpu_relax to C sparc: Fix sparv9 multiarch build sparc: Remove ununsed ifunc assembly macros (and likely more) 3. do a targeted "sed 's/SHARED/PIC/g'" on a bunch of "sysdeps/sparc/**.S" files.

Seems like masking <glibc-2.27 will cause problems as libnsl:0 (which is a dependency of opensp, then a dependency of openjade, then a dependency of po4a, which is required for man-db ( nls ? >=app-text/po4a-0.45 ) ) requires <glibc-2.26.
> 3. do a targeted "sed 's/SHARED/PIC/g'" on a bunch of "sysdeps/sparc/**.S" > files. Following this, I did this as a work-around: # ebuild /usr/portage/sys-libs/glibc/glibc-2.25-r9.ebuild fetch unpack # find /var/tmp/portage/sys-libs/glibc-2.25-r9/work/glibc-2.25/sysdeps/sparc/ -name \*.S -exec sed -i 's/def SHARED/def PIC/' {} \; -print # ebuild /usr/portage/sys-libs/glibc/glibc-2.25-r9.ebuild compile install # ebuild /usr/portage/sys-libs/glibc/glibc-2.25-r9.ebuild qmerge This gave me a succesful install and so far, nothing has broken. Re-emerging @world now, but that will likely take a day or two on this thing. (Netra T1 200)
Queued the fix for 2.27 as: https://github.com/gentoo/glibc/commit/fec498315526476aaf05260677d58f5ac5adaf00
Created attachment 517822 [details, diff] Patch for seraph@xs4all.nl sed changes Following seraph@xs4all.nl method I have prepared a patch. I have done full "emerge -e @world" twice successfully. First I followed seraph's method from comment 17 then I made a patch to put in /etc/portage/patches/sys-libs/glibc-2.25-r9/ So I could do my @world rebuilds without pause. Two full cycles using the patch so seraph's method looks good. I am not up to tinkering with ebuild's to the extent of running find/sed between steps. Thank you. Enjoy, Jim
Fixed in sys-libs/glibc-2.27-r3 Should we maybe also backport this to our 2.26 ?!

Clickable link: https://github.com/gentoo/glibc/commit/dec42d1257717054c08b8293d799e640e94df1d7 At the risk od stating the obvious. 2.26 will require a lot more fixes as described in #c15 than just start.S tweak.
