[PATCH, libiberty, gcc]: Introduce xasprintf to libiberty and use it in gengtype

Hello! Based on a suggestion from [1] and on previous work by Manuel and Ben. The new code is almost the same as existing asprintf.c, but uses recently added xvasprintf. Thes patch removes local xasprintf definition from gengtype.c and uses the new one there. libiberty/ChangeLog: 2014-12-24 Ur

Flatten tree.h and tree-core.h (Version 2)

This patch flattens tree.h and tree-core.h. This is a revised patch that does not include tree-core.h as a result of flattening. I removed the includes in tree.h and tree-core.h except for the include of tree-core.h in tree.h. I modified genattrtab.c, genautomata.c, genemit.c, gengtype.c, ge

I am committing the attached patch, which adds support for the mul.x and umul.x instructions, which compute the high 32 bits of a 64-bit result for a 32-bit multiply (signed and unsigned). These instructions are enabled by default for moxiebox-* configurations. This patch also updates the add, s

[PATCH] combine: Correct cost calculation and display for split I2

If we have split a parallel I2 to two insns, we will count its RTL cost twice. This currently does not matter since the cost is 0 always (it is not a single set insn), but let's fix it anyway. Also do not display the fake I1 in the cost calculation in the dump file. Tested on powerpc64-linux. O

[PATCH] rs6000: Fix the dlmzb. testcases

The dlmzb. instruction requires an 8-byte aligned operand. The testcases try to enforce that by passing an arg as "long long *", but current GCC still assumes an alignment of 1 (correctly I think -- the pointer is only used as pointer to char). This patch changes the testcases to explicitly have

[PATCH] simplify-rtx: Generalize (and X (ior (not X) Y) -> (and X Y)

The existing transform (and X (ior (not X) Y) -> (and X Y) has two shortcomings: it only handles identical RTX for X, i.e. registers, not e.g. subregs of registers; and it only handles the case where the NOT is the first arm of the IOR (it can be the second arm e.g. if the first arm is a NOT as

[Patch, MIPS] Remove some multilibs from mips-mti-linux-gnu target

This patch removes mips32[r1] and mips64[r1] from the list of mips-mti-linux-gnu architectures built with -mnan=2008. They should never have been included since these architectures do not support the ieee 2008 format (GCC warns and ignores the nan flag). The recent changes to glibc to use -Werror

Hello, The attached patch fixes an issue reported a couple of years ago in Bug 51891 (https://gcc.gnu.org/bugzilla/show_bug.cgi?id=51891). The problem is caused because classes without instance variables have no ivar list at all, so that their ivars pointer is NULL, but the code in class_cop

[PATCH] ubsan: Do not run the testsuite if ubsan does not work at all

I normally build with --disable-libsanitizer, because the sanitizers testresults are very unreproducable, so just annoying noise. This however makes most (all?) ubsan testcases fail, since they want to load a shared library that does not exist. This patch disables the ubsan testcases if a trivial

C++ PATCH for c++/63522 (ICE with unexpanded parameter pack)

Things later in compilation were getting confused because we didn't catch the unexpanded parameter pack soon enough. While looking at this I also fixed a location issue with the error about a parameter pack before the end of a class template parameter list, and avoided some follow-on errors wh
