+Subject: [PATCH] gcc/configure: Fix check for assembler section merging
+ support on Arm
+Message-ID: <20241227214756.1059146-1-thiago.bauermann@linaro.org>
+
+In 32-bit Arm assembly, the @ character is the start of a comment so
+the section type needs to use the % character instead.
+
+configure.ac attempts to account for this difference by doing a second
+try when checking the assembler for section merging support.
+Unfortunately there is a bug: because the gcc_GAS_CHECK_FEATURE macro
+has a call to AC_CACHE_CHECK, it will actually skip the second try
+because the gcc_cv_as_shf_merge variable has already been set:
+
+  checking assembler for section merging support... no
+  checking assembler for section merging support... (cached) no
+
+Fix by using a separate variable for the second try, as is done in the
+check for COMDAT group support.
+
+This problem was noticed because the recent binutils commit
+d5cbf916be4a ("gas/ELF: also reject merge entity size being zero") caused
+gas to be stricter about mergeable sections without an entity size:
+
+configure:27013: checking assembler for section merging support
+configure:27022: /path/to/as   --fatal-warnings -o conftest.o conftest.s >&5
+conftest.s: Assembler messages:
+conftest.s:1: Warning: invalid merge / string entity size
+conftest.s: Error: 1 warning, treating warnings as errors
+configure:27025: $? = 1
+configure: failed program was
+.section .rodata.str, "aMS", @progbits, 1
+configure:27036: result: no
+
+In previous versions of gas the conftest.s program above was accepted
+and configure detected support for section merging.
+

+Tested on armv8l-linux-gnueabihf.
