From 22a7e82c200d01d12e34e757e86dc9796a9bf085 Mon Sep 17 00:00:00 2001 From: Patrick Palka Date: Fri, 18 Dec 2020 11:52:24 -0500 Subject: [PATCH] libstdc++: Fix build failure on AArch64 ILP32 [PR98370] This should fix a build failure on AArch64 ILP32 due to int32_t mapping to long int instead of int on this platform, which causes type deduction to fail in the below call to std::max as reported in the PR. libstdc++-v3/ChangeLog: PR libstdc++/98370 * src/c++17/floating_to_chars.cc (__floating_to_chars_shortest): Provide explicit template arguments to the call to std::max. --- libstdc++-v3/src/c++17/floating_to_chars.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/libstdc++-v3/src/c++17/floating_to_chars.cc b/libstdc++-v3/src/c++17/floating_to_chars.cc index 6470fbb0b95..3f46bce7a15 100644 --- a/libstdc++-v3/src/c++17/floating_to_chars.cc +++ b/libstdc++-v3/src/c++17/floating_to_chars.cc @@ -977,7 +977,7 @@ template // fd.exponent contain all of the information needed to format the // number in fixed notation "as if by std::printf" (with precision // equal to -fd.exponent). - const int whole_digits = max(mantissa_length + fd.exponent, 1); + const int whole_digits = max(mantissa_length + fd.exponent, 1); const int expected_output_length = fd.sign + whole_digits + strlen(".") + -fd.exponent; if (last - first < expected_output_length) -- 2.30.2
