commit 547a601cf3cd364433d9434bde3f3514cfe5e52a
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit 63317c25c2f3d1146c4a0d20de91500bd510113d
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit 5d27301ad9dd34b6c84f956ffa0f93b710657488
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit d4c66b811bca822bf6e6e31c03cc523b52410e9a
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit 95e3fbd306746e7d040ae8fb4201f488cc85819e
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit f55e6c19901cca2485ca41f6def97c6ef152ebb7
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit 99f78ebdaa76942aa668e984864224a458dbcdd1
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit c48bac4d0e5525fa8c8034c8d5839d5e99cee888
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit 12ca143f4f19e09d48f37ab4c341f7c0d3e29d25
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

* [glibc/azanella/clang] Remove err-ldbl.h

commit 687ac12d757214494f9a97c3d5c7ea7c2e7f60ae
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.

commit bff6b10288d2a9085473ba364f033bc5aa791992
Author: Adhemerval Zanella <adhemerval.zanella@linaro.org>
Date:   Mon Feb 28 19:49:31 2022 -0300

    Remove err-ldbl.h
    
    The functions which require different alias to long double depending
    of the ABI now uses a set os macros that defines the expected alias
    on the function prototype, instead of redefine them using the
    __LDBL_REDIR_DEC macros.
    
    All err internal usage are also replaced to use internal alias
    instead.
    
    Checked on x86_64-linux-gnu and powerpc64le-linux-gnu.
