--- Comment #7 from Jakub Jelinek <jakub at redhat dot com> ---
So, I've tried your patch on my short #embed testcase:
unsigned char a[] = {
#embed "cc1plus"
};
with the #embed patchset for GCC, where cc1plus is 273372376 bytes long binary.
Assembly for this from the gcc is 1328371852 bytes long, just
.file "embed-11.c"
.text
.globl a
.data
.align 32
.type a, @object
.size a, 273372376
a:
.byte 127
.string "ELF\002\001\001\003"
.string ""
.string ""
...
.string

.string ""
.byte 0

Now, if I hand edit this to replace the first .byte up to the last one
including .string etc. directives in between with
cat cc1plus | base64 | sed 's/^/\t.base64\t"/;s/$/"/'
the new assembly is 422048853 bytes.

049aaf9fdb9cf6f84fd54984ab032ac0 embed-11_.o
So, this looks good to me.
