Shouldn't the release have a tag on git?
It doesn't seem to be there: https://gcc.gnu.org/git/?p=gcc.git;a=tags
git tag gcc-7_2_0-release 1bd23ca8c30f4827c4bea23deedf7ca33a86ffb5

After downloading and verifying the releases on
ftp://ftp.gnu.org/gnu/, I found that the maintainers used 1024 bit DSA
keys with SHA1 content digests. 1024 bit keys are considered to be
susceptible to realistic attacks, and SHA1 has been considered broken
for some time.

When implementing the RISC-V port, I took the name of this macro at
face value. It does seem that we should follow Andrew's advice and
set it to 1. (For your examples, doing so does improve code
generation.)
We'll submit a patch if the change doesn't regress.

Here’s a more extreme example:
- https://cx.rv8.io/g/2HWQje
The bitfield type is unsigned int, so one or two 32-bit loads should suffice
(depending on register pressure). GCC is issuing a lw at some point in the asm.
struct foo {
unsigned int a : 3;
unsigned int b : 3;
unsigned int c : 3;
Hi,
Is there any reason for 3 loads being issued for these bitfield accesses, given
two of the loads are bytes, and one is a half; the compiler appears to know the
structure is aligned at a half word boundary. Secondly, the riscv code is using
a mixture of 32-bit and 64-bit adds and shifts. Thi

Is there a setup for writing and running as part of the test
suite unit tests that exercise internal GCC functions like
error and warning? I ask because of a couple of bugs that
were recently reported for the %s directive in GCC's

Everything that can be done with cc0 can be done with the new representation,
at least theoritically, although this can require more work.

When compiling the following code:
int* ptr = nullptr;
delete ptr;
GCC 7.1 on x86_64 generates a delete-operator-related call instruction in the
resulting program with both -O2 and -O3 optimization flags. This is a nonsense
piece of code, indeed, but imagine a class that has an owning raw poin
