Subject: [PATCH] mips-linux-nat: Define _ABIO32 if not defined
|
||||
|
||||
This helps building gdb on mips64 on musl, since
|
||||
musl does not provide sgidefs.h this define is
|
||||
only defined when GCC is using o32 ABI, in that
|
||||
case gcc emits it as built-in define and hence
|
||||
it works ok for mips32

Subject: [PATCH] Dont disable libreadline.a when using --disable-static
|
||||
|
||||
If gdb is configured with --disable-static then this is dutifully passed to
|
||||
readline which then disables libreadline.a, which causes a problem when gdb
|
||||
tries to link against that.
|
||||
|
||||
To ensure that readline always builds static libraries, pass --enable-static to
|
||||
the sub-configure.

Build fix for MIPS with musl libc
|
||||
|
||||
The MIPS specific header <sgidefs.h> is provided by glibc and uclibc
|
||||
but not by musl. Regardless of the libc, the kernel headers provide
|
||||
<asm/sgidefs.h> which provides the same definitions, so use that
|

instead.

The POSIX document says

The pthread_sigmask() and sigprocmask() functions shall fail if:

|

[EINVAL]
|
||||
The value of the how argument is not equal to one of the defined values.
|

|

and this is how musl-libc is currently doing. Fix the call to be safe
|

and correct

Subject: [PATCH] Define alignof using _Alignof when using C11 or newer
|
||||
|
||||
WG14 N2350 made very clear that it is an UB having type definitions
|
||||
within "offsetof" [1]. This patch enhances the implementation of macro
|
||||
alignof to use builtin "_Alignof" to avoid undefined behavior on
|
||||
when using std=c11 or newer
|
||||
|
||||
clang 16+ has started to flag this [2]
|
||||
|
||||
Fixes build when using -std >= gnu11 and using clang16+
|
||||
|
||||
Older compilers gcc < 4.9 or clang < 8 has buggy _Alignof even though it
|
||||
may support C11, exclude those compilers too

When running the configure check "checking for ELF support in BFD", LDFLAGS
|
||||
were not being passed in to libtool. In OE/YP, we need these flags when using
|
||||
uninative due to the games we play with the dynamic loader.
|
||||
|
||||
If a version of libzstd was built against a newer glibc, it would need
|
||||
newer pthread symbols which it wouldn't find with the system linker. At
|
||||
runtime this isn't an issue as it would be switched to use uninative but we
|
||||
pass flags in LDFLAGS to allow this.
|
||||
|
||||
The comments say LDFLAGS are used but it was dropped in this commit:
|
||||
|
||||
https://sourceware.org/git/?p=binutils-gdb.git;a=commit;h=5218fa9e8937b007d554f1e01c2e4ecdb9b7e271
|
||||
|
||||
and probably needs to be put back upstream.
|
||||
|
||||
The bug is rare to reproduce as it depends on the host libzstd was built
|
||||
against.
