2023-07-14gcc: don't pass --enable-standard-branch-protectionRoss Burton
By changing the default code generation of GCC we're inadvertently breaking the GCC test suite, which has ~120K+ more failures when run for aarch64 compared to x86-64. This was because the generated code fragments included the BTI instructions, which the test case wasn't expecting. We can't tell the tests globally to run without branch protection, as that will break the tests which also turn it on. Remove the enabling of branch protection by standard in GCC, we'll enable it in the tune files instead.

2021-06-08gcc: enable branch protection by standardRoss Burton
Pass --enable-standard-branch-protection. This is an aarch64-specific option (currently) which does nothing on other targets. On aarch64 this generates code uses BTI/PAC instructions to mitigate Return Orientated Programming attacks. This approach is backwards compatible and the code size/performance impact is typically negliable.

2018-12-26gcc: Drop gcc-cross-initial and use gcc-cross insteadRichard Purdie
We need a libgcc to build glibc. Tranditionally we therefore build a non-threaded and non-shared compiler (gcc-cross-initial), then use that to build libgcc-initial which is used to build glibc which we can then build gcc-cross and libgcc against. Firstly, we can drop the glibc dependency from gcc-cross, *if* we make two changes: a) specify the minimum glibc version to support in a configure option b) create a dummy limits.h file so that later when glibc creates one, the headers structure has support for it. We can do this with a simple empty file Once gcc-cross is libc independent, we can use it to build both libgcc-initial and then later libgcc. libgcc-initial is tricky as we need to imitate the non-threaded and non-shared case. We can do that by hacking the threading mode back to "single" even if gcc reports "posix" and disable libc presence for the libgcc-intial build. We have to create the dummy limits.h to avoid compiler errors from a missing header. glibc will fail to link with libgcc-initial due to a missing "exception handler" capable libgcc (libgcc_eh.a). Since we know glibc doesn't need any exception handler, we can safely symlink to libgcc.a. With those changes, gcc-cross can be used in all places and we only need one build of gcc for each architecture. For some reason ifunc was being disabled on mips prior to these changes but afterwards became enabled but caused assertion failures. This is therefore disabled until we can debug that.

2016-02-02gcc-configure-common.inc: drop --enable-target-optspace from configureAndre McCurdy
Configuring gcc with --enable-target-optspace (which causes gcc to append "-g -Os" to the default CFLAGS_FOR_TARGET and so force libgcc etc target libraries to always be optimised for size) dates back to the very first commit in oe-core git in 2005 (for gcc 3.4.3). Configuring gcc with --enable-target-optspace is not done widely elsewhere (it's not used for Ubuntu or Fedora host gcc, the Linaro binary toolchain or in Buildroot since early 2015). Sometime around gcc 4.5.x it caused problems for powerpc and so was disabled for that architecture: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810 This patch removes --enable-target-optspace completely (ie powerpc is no longer a special case) and allows optimisation of libgcc etc to be controlled directly by the flags present in TARGET_CFLAGS.

2015-11-16gcc: Update default Power GCC settings to use secure-pltMark Hatle
The gcc default, bss-plt, will cause errors when using the prelinker. All other distributions that I am aware of are using the the secure-plt. For an explanation of the differences, the gcc docs: Current PowerPC GCC accepts a `-msecure-plt' option that generates code capable of using a newer PLT and GOT layout that has the security advantage of no executable section ever needing to be writable and no writable section ever being executable. PowerPC ld will generate this layout, including stubs to access the PLT, if all input files (including startup and static libraries) were compiled with `-msecure-plt'. `--bss-plt' forces the old BSS PLT (and GOT layout) which can give slightly better performance. The security of the new PLT and ability to run the prelinker outweigh any performance penalty. The secure-plt is enabled by default. The old bss-plt can be enabled by selecting 'bssplt' in the DISTRO_FEATURES.

2015-01-29arch-mips.inc: Change definition of TRANSLATED_TARGET_ARCHMark Hatle
[YOCTO #7230] In certain system configurations TRANSLATED_TARGET_ARCH will not expand in the right order for gcc-cross-candian-mips64n32 to be generated properly. This will cause SDKs to fail to generate properly. Changing the global definition of TRANSLATED_TARGET_ARCH always expands the ABIEXTENSION, which causes the OVERRIDES to pick it up as well. This effectively defines a new class of overrides for the 'n32'. The side effect is that we need to duplicate some mips64 overrides, and redefine others that were previously 'n32' or 'mips64' exclusive to have the correct semantics.

2014-12-03gcc: Rework shared workRichard Purdie
The current implementation of shared work for gcc is at best confusing. It relies on the fetch/unpack/patch tasks having exactly the same stamps and if this gets broken for some reason, its hard to figure out what the problem is. It also leads to complex code in bitbake. The benefits of shared work for gcc are clear but a better approach is needed. This patch adjusts things so that a single new recipe (gcc-source) provides the fetch/unpack/patch/preconfigure tasks, the rest of gcc simply depends on these tasks and have no fetch/unpack/patch tasks of their own. This means we should get the significant benefits (disk usage/performance) of the single source tree but in a way which has less potential for problems and is easier for people to understand. The cost is an extra recipe/some inc files which is probably a good tradeoff.

2014-08-15gcc: update compiler architecture to match gcc-runtime (armv6, armv7a)Peter A. Bigot
The gcc-runtime recipe builds the gcc libraries including libstdc++ with $TARGET_CC_ARCH flags, which include -march=FOO flags that affect whether atomic instructions are available. This causes an ABI incompatibility when the compiler by default generates code for less capable architectures. For example, gcc-runtime libraries on a Cortex-A8 are built with a different C++11/C++14 mutex implementation than is used code compiled outside OE and without architecture-specific flags. This commit fixes the problem specifically for ABI issues related to atomic instructions available in ARMV6 and subsequent architectures. Other ABI incompatibilities may remain in other architectures.

The gengtype patch we apply to gcc aims to ensure that the build and host config headers don't get confused. We're seeing build failures where both headers have been included, likely due to a race over the configuration files. It seems the gengtype-lex.c file isn't being regenerated when it should and the unconditional inclusion of bconfig.h is resulting in these issues. The fix is therefore to remove the file, forcing its regeneration.

On mingw were were seeing two issues, firstly that the if statements meant the values we wanted weren't being set, the second that the include paths were still wrong as there was no header path set. To fix the first issue, the #ifdef conditionals were removed, we want to set these things unconditionally. The second issue is addressed by setting the NATIVE_SYSTEM_HEADER_DIR variable here (it was already set in t-oe).

If sed-native is built before these programs, hardcoded paths to sed-native can end up in scripts and other parts of the system which may cause issues if they are later used from sstate and sed-native is not installed. To avoid this, this patch changes the global site configuration to specify that plain "sed" is fine to be used. We need to spell this out for gcc since it doesn't see the site files since we don't autoreconf it. We can remove the values from libtool. We tell perl to use "/bin/sed" since it requires a path and the system sed should be just fine for it.

2012-09-26gcc-configure-cross: factor out --enable-threads argument into ${GCCTHREADS}Phil Blundell
This allows BSPs for architectures with no thread support to set (for example) "GCCTHREADS=no" without having to override all the other configure parameters.

2012-07-05gcc: fix collect2 host contamination problem properlyRichard Purdie
We added the autoconf cache line a while back to ensure that configure doesn't poke into some hardcoded host paths looking for things it shouldn't. Applying it as part of do_configure wasn't getting it to the do_compile tasks where much of the configure scripts are run by gcc. This changes it to a simple export to ensure it reaches the places it needs to and truly gets rid of the cross compile badness messages from the logs.

2012-04-30gcc-configure: Render --with-local-prefix harmlessKhem Raj
this option by default points to /usr/local no matter what so we cant let it sit on sidelines otherwise it will access host machine's /usr/local which may not be desired. So disable this option.

2012-04-30gcc-configure: Pass distinct target flagsKhem Raj
When building gcc-cross-canadian libgcc is built using headers from gcc-crosssdk and not the target sysroot because we do not pass proper CFLAGS for target bits so it ends up using CFLAGS that were meant for compiling canadian gcc itself. It does not show up as a problem when building SDK with eglibc because eglibc-nativesdk and eglibc have identical headers. The problem shows up clearly when you try to build uclibc based meta-toolchain since then nativesdk libc and target libc are different (From OE-Core rev: 0e904103e9bd7fdb31bfcc129067511f9f45701b) Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2012-04-15gcc-configure-common.inc: Stop gcc looking at build system pathsRichard Purdie
There were puzzling failures when you make a force recompile of any gcc component. The error was in do_configure with cross-compilation badness being detected in config.log files. gcc is different in that many of the config.log files are generated during the do_compile phase. This means this host contamination issue has always been present but only shows up on a rebuild. The fix is to force the appropriate configuration variable to "none required" then gcc won't look in the bad locations.
