+Subject: [PATCH 3/3] Allow setting target sysroot with ESYSROOT env var for
+ cross-compilers
+
+The variable is ignored for native compilers, when it matches BROOT, and
+when the target machine does not match CHOST (if set). The --sysroot
+command line option takes precedence.
+
+The CHOST check is necessary for a Canadian Cross. In that case, two
+cross-compilers are invoked, but only the one matching CHOST should have
+its sysroot set by ESYSROOT.

+
+These tests expect the diagnostic from -Wcomplain-wrong-lang but

+with -Wno-complain-wrong-lang.
+
+gcc/testsuite/ChangeLog:
+ * gfortran.dg/ISO_Fortran_binding_17.f90: Pass -Wcomplain-wrong-lang.
+ * gfortran.dg/c-interop/allocate-errors.f90: Likewise.
+ * gfortran.dg/c-interop/establish-errors.f90: Likewise.
+ * gfortran.dg/c-interop/section-errors.f90: Likewise.
+ * gfortran.dg/c-interop/select-errors.f90: Likewise.

+Subject: [PATCH] Default to -mfpmath=sse on x86 with time64
+
+Our time64 stages already default to `-mfpmath=sse`, so let's have
+the time64 flag implicitly enable it as the default to make things more
+consistent. Furthermore, this also improves compatibility with clang
+that always enables it whenever the target architectures supports SSE.
+
+Note that this works only if `-march=` with SSE support is specified.
+We could technically improve the consistency even further by raising
+the default `-march=`, but that seems a bit intrusive and probably
+unnecessary, given that the vast majority of Gentoo users and/or
+upstream projects will specify `-march=`.

+Subject: [PATCH] config: nvptx: fix bashisms with gen-copyright.sh use
+
+Providing parameters to `.` when sourcing is a bashism and not supported
+by POSIX shell which causes a build failure when compiling a toolchain
+for nvptx-none with dash as /bin/sh.
+
+gen-copyright.sh takes a parameter for the format of copyright notice
+required. Switch that to using an environment variable `NVPTX_GEN_COPYRIGHT`,
+although this could be changed to a function if desired (just more churn
+in gen-copyright.sh then).

+ * config/nvptx/gen-copyright.sh: Read NVPTX_GEN_COPYRIGHT envvar.
+ * config/nvptx/gen-h.sh: Set NVPTX_GEN_COPYRIGHT.

+Subject: [PATCH] Makefile.tpl: Implement per-stage GDCFLAGS [PR116975]
+
+Hi,
+
+This patch implements STAGE1_GDCFLAGS and others to the configure
+machinery, allowing the GDCFLAGS for each bootstrap stage of building
+gdc to be overriden, as is the case with CXXFLAGS for other front-ends.
+
+This is limited to just the generation of recipes for the
+configure-stage-gcc and all-stage-gcc, as a D compiler is not optionally
+needed by any other module.
+
+OK for mainline?
+
+Regards,
+Iain.

+These changes are meant to fix gcc-15 for some musl-32 bit platforms.
+They involve fixing some declarations (e.g define readdir, not
+readdir64) and correcting the layout of some structs from time32 to
+time64.
+
+The fixes for the function declarations come from
+https://github.com/dlang/dmd/pull/21639 and the struct definitions
+come from https://github.com/dlang/dmd/pull/21249, but with a slighter
+older version compared to the one that was merged in order to support
+older compilers that don't have bitfields support.
+
+Lastly there's a small improvement to try to fix the butchered API by
+making the timespec struct constructible with either 1 or 2
+arguments. Outside of musl the struct is constructible with 0, 1, or 2
+arguments. With the bitfield variant of the fix this issue is
+resolved, but, with older compilers it is not accessible.

+Subject: [PR-21639] [PATCH] druntime, musl: Remove unused __USE_FILE_OFFSET64 bindings
+
+As pointed out in #21249, Musl doesn't implement *64 versions of these
+functions because off_t is always 64 bits. However there are aliases
+defined if `_USE_LARGEFILE64_SOURCE` is true.
